Session 1, March 9, 2001



      EXAMINATION OF CAPT KYLE (CONTINUED):



                CAPT MACDONALD:   Let the record 



reflect that the members, the parties, and the 



counsel for parties and counsel for the court are 



again present. 



      Again, I would like to remind every one to 



speak slowly and clearly into the microphones so that 



our interpreters can provide the best possible 



simultaneous translation.  



      Sir, we have some procedural matters. 



      The first matter, we've received a request by 



Lt Cmdr Pfeifer for assignment of additional 



counsel.  This request is dated 8 March, 2001.  It 



has been marked J.  And I am informed that Lieutenant 



Dan Shanahan from Yokosuka, Japan from the NILSO 



(phon.) will be flying in this weekend to assist in 



his  epresentation. 



     In addition sir, the Commander in Chief US 



Pacific Fleet Admr Fargo has responded to -- 



inaudible -- that request has been denied.  Copies 



have been distributed to counsel.  I would like that 



marked as next exhibit in order. 



      And sir, the court requested that counsel for 



the court tried to locate a copy of the signed watch 


Page                                                 2


bill.  One was located on board the Greenville 



yesterday, and has been provided.  I would like to 



have this marked as next court evidentiary exhibit in 



order.  Copies have been provided to the parties, and 



I'm providing copies now to the members of the 



court. 



      Sir, one final point, as we discussed 



yesterday, the ship's sonar search plan was located.  



The court members had an opportunity to review the 



sonar search plan, and are satisfied that the search 



plan was properly prepared by the Greenville, and the 



court does not desire that it be introduced as an 



evidentiary exhibit.  They are satisfied that the 



document was properly prepared and executed. 



      Sir, that's all that counsel for the court has.



                VADM NATHMAN:   Procedural matters 



from counsel?



                MR. GITTINS:   I would just ask for 



the sonar -- the sonar log we just talked about -- is 



that a classified document?



                VADM NATHMAN:   It's secret, yes. 



                MR. GITTINS:   At some, point I would 



like to briefly review it, yes. 



                CAPT MACDONALD:   We'll do that at 



the first break.

                LCDR YOUNG:   Can we clarify the 



exhibit -- the watch bill?



                CAPT MACDONALD:   For the record, the 



watch bill has been entered as Exhibit 41. 



                LCDR YOUNG:   Thank you. 



                MR. GITTINS:   We were provided the 



copies of the watch bill, sir, was it ascertained how 



the markings the circles and et cetera were added to 



that.  Is that something that identified the 



watchstands at the time of the mishap?



                CAPT MACDONALD:   Sir, we don't know 



at this point.  We can certainly -- questions are 



going to be asked of witnesses brought before the 



court as to how the document was prepared.  



      At this point, we only know that we've got the 



original document. 



                MR. GITTINS:   Thank you, sir.



                VADM NATHMAN:   Counsel for Mr. 



Coen.    



                LCDR FILBERT:  (Indicates 



negatively.)   



                CAPT MACDONALD:   The court re-calls 



Captain Tom Kyle to the stand. 



      Captain Kyle, if you would please re-take your 



seat in the witness box.  Sir, I would remind you 


Page                                                 4


again that you are under oath. 



                THE WITNESS:   Sir. 



                CAPT MACDONALD:   Captain, before we 



begin, I understand that you will be testifying 



concerning information contained on the slides that 



you prepared for your testimony.  In addition, a hard 



copy of those slides, you have written in some notes 



to aid you in your testimony? 



                THE WITNESS:   That's correct.  



                CAPT MACDONALD:    Commander 



Harrison, would you have the -- Captain Kyle's notes 



marked as next court's evidentiary exhibit in order? 



                LCDR HARRISON: These notes will be 



marked as Exhibit 42. 



                CAPT MACDONALD:   Thank you. 



Q     (By Capt MacDonald)  Commander Harrison, would 



you retrieve the floor exhibit?  



      Good morning, captain. 



A     Good morning. 



Q     Captain, yesterday you testified that one of 



the reconstructions that was done was performed by 



DEVRON 12 (phon.) is that correct? 



A     That's correct. 



Q     And as part of the reconstruction effort, did 



you ask DEVRON 12 to determine whether any of the 


Page                                                 5


sonar contacts that they evaluated was in fact the 



Ehime Maru? 



A     Yes, I did.  In the report DEVRON 12 gave to 



me, they said that there was very close correlation 



between the contact being tracked as Sierra 13 to the 



reconstructed track that they came up with for the 



Ehime Maru which is consistent with our conclusion as 



well. 



Q     Sir, referring you again to the chart that you 



see up on the screen which is the S 13 reconstruction 



chart.  There were a lot of questions yesterday,  



particularly from Admr Nathman concerning 



signal-no-noise ratio.  



      Is it possible to get range information from 



signal-to-noise ratio alone?



A     I think it's a very important point that the 



answer is sort of yes and no.  We have learned 



through experience that low or medium S&Rs are not a 



determination of range.  And we train ourselves -- 



our operators and ourselves -- to not draw any 



conclusion from a low S&R contact. 



      There can be a very large or loud contact that 



may present aspects where the S&R drops off, it's 



very common for a ship to have a null area.  An 



example would be a large tanker, for instance, off 


Page                                                 6


the bow, his sound will be masked by the cargo he's 



carrying, and his large size in front of him.  His 



engine sound would be masked, so although the contact 



would be allowed and heavy contact maybe at close 



range, his S&R maybe low.  



      On the other hand, we always view rising S&R 



and strong S&Rs as an indication of a potential close 



contact. 



      So low S&R is not an indication of range at 



all.  We try not to draw any inference on range, of a 



low or medium S&R.  But a high S&R says that the 



contact may be coming close. 



Q     I would like to draw your attention to the 



graph on the right-hand side, the range versus time. 



      If the commanding officer or the officer of the 



deck had looked at the fire control solution just 



prior to coming to periscope depth, what would this 



data have told them? 



A     It really depends.  It's an important point to 



understand that if anyone had gone to one of the 



other unused consoles on the fire control system on 



the day in question, as I understand the situation 



there was only one operator there, one console being 



used by that operator, so there were three additional 



consoles that were not being used.  


Page                                                 7


      If the officer of the deck or the captain or 



anyone else in the control room decided to go to one 



of those consoles and to review the contacts being 



tracked, independently, and he had just called up the 



solutions on those contacts, Sierra 13, Sierra 14, 



Sierra 12 -- the only thing he would have seen up 



there would have been system solution, not the trial 



solution that is being depicted that probably was on 



the fire control operator's screen. 



      So if he, in preparation to go to periscope 



depth, had picked up Sierra 13 and looked at it, he 



would have looked at this solution up here.  That is 



what would have been depicted. 



      Now, I should add that the solution if you 



looked at the analysis display where the processing 



is being done, if he called up that display, which is 



called "mate" that I showed in the demonstration 



earlier in the week, it probably would have indicated 



in the last few minutes prior to going to periscope 



depth that the solution was not very accurate and 



that would have been readily apparent to him.  



      On the other hand, if he had gone to a 



different display -- there is an option to go to a 



geographic display that just has a top down look of 



own ship's position with the contacts being tracked 


Page                                                 8


geographically around the ship.  If he had just 



looked at those displays, they would have just shown 



the system positions relative to own ship, with no 



indication of quality of solution apparent. 



      Depending on what and if an independent look 



was done on the screens, you can have different 



answers coming out.  



      On the other hand, if the independent person 



went and looked at the fire control operator's 



screen, I am fairly confident he would have seen a 



display for Sierra 13 that was probably reflecting 



this solution that was in development. 



      So it's -- it's a very important question, and 



different answers could have come out depending on 



what the actual scenario that occurred prior to the 



going to periscope depth. 



Q     It seems to me there is a big "if" in what 



you've just said.  The "if" being if it had been in 



check.  Is the officer of the deck required to check 



the fire control solution? 



A     He's required to satisfy himself that it's safe 



to go to periscope depth.  He can do that in a number 



of ways.  He can do that by his own analysis.  On a 



normal day without equipment degradation, he can 



probably do that using the AVSDU display, do some 


Page                                                 9


mental analysis, maybe some calculations on his own.  



      Most officer of the decks that I see will go to 



the fire control screen and verify his mental picture 



of what the fire control operator is doing -- that 



would be the normal process -- report the solution on 



this contact, and he would check what he was coming 



up with independently.  Yes, the officer of the deck 



should be involved in looking at the fire control 



solution. 



      The commanding officer is required to concur 



that it's safe to go to periscope depth.  So 



depending on the commanding officer's level of 



confidence in the OOD's description of how he 



verified -- how the officer of the deck verified that 



it was safe to go to periscope depth, the captain may 



or may not do an independent review of the fire 



control screen.  



      That's -- that's -- he has to be satisfied that 



he has enough information in his own mind that it's 



safe to go up. 



Q     Is that stated anywhere by regulation in the 



submarine force, or is that just good practice? 



A     No, it is stated in the standing orders for 



going to periscope depth -- this integrative process 



of evaluation, the officer of the deck's 


Page                                                 10


responsibilities, and the fact that the captain must 



concur and give permission to go to periscope depth. 



Q     So the prudent action is to check all of the 



available sensor data that the officer of the deck 



has or the captain has in the control room before you 



do that?



A     Or in sonar, if you have to go to sonar.  



      If you are puzzled or you need more information 



about a contact, and you think sonar may have some 



answers -- open that door to sonar, and ask the sonar 



supervisor or have the sonar supervisor come out and 



report on the added information required. 



                RADM SULLIVAN:   So, captain, what 



you're kind of telling me here, at least when we 



think through this in this process -- it's not as if 



the accounting officer of the deck, if it's the 



officer of the deck, or the CO, or whoever is up one 



of the senior officers for the accounting of the 



ship -- it's not as if they stand between the 



periscopes and wait for the information to flow to 



them and be told it's safe to go.  There is very much 



involvement on the part of those senior 



watchstanders, or the XO, or CO -- whoever is 



involved in the exercise -- in getting to periscope 



depth to reach down into the screens, page through 


Page                                                 11


the fire control systems, to search the data 



themselves? 



A     That's correct, sir.  



      He must be satisfied -- he has enough data and 



he's comfortable, and he understands the contact 



situation and he must go -- dig as deep has he needs 



to be to be comfortable that he understands the 



contact picture and its safe to go to periscope 



depth.  And it may mean reaching all the way back and 



going into the sonar room itself, and talking to the 



operators sitting on the consoles who are listening 



to the contact. 



      And the degree that you have to go -- how far 



you have to dig -- is dependent upon the situation.  



But he has to go through every contact in his mind -- 



every contact being tracked, and resolve in his own 



mind that it's safe to go to periscope depth with 



respect to that contact. 



                RADM SULLIVAN:   So to say it 



another way, maybe we've discussed here prior to your 



testimony here about makeup of a typical sonar team, 



fire control team, people that add information into 



solving this problem, that the officer who is conning 



the ship, who is involved, should probably have -- is 



stepping back the further to get integration to have 


Page                                                 12


the larger view, if you will, of the entire 



situation. 



                THE WITNESS:   That's correct. 



                RADM SULLIVAN:   And each of the 



operators, while having a vital piece of information, 



necessarily isn't knowledgeable of the entire 



picture?



                THE WITNESS:   That's correct.  The 



officer of the deck is trained basically to take the 



whole picture.  He's the center of all the 



requirements around the ship -- what needs to be done 



and what the objective is.  He is sort of, if you 



will, the quarterback of this whole team of people, 



and he has the entire play in mind.  And the team 



obviously works better, like any team, the more he 



can disseminate the objectives and what's being done 



in his overall situation, so that all the players, 



all the participants, are understanding what the 



objectives are that we're trying to do and what the 



plan is, you know. 



      For instance, in a normal periscope depth 



procedure, it says to have a briefing of all your key 



watchstanders.  The officer of the deck should 



conduct a briefing including all the sensor 



operators -- the ESM, the radar intercept folks, the 


Page                                                 13


radiomen, the sonar men, the fire control men -- and 



discuss the whole plan for going to periscope depth 



to get them all thinking on the same -- towards the 



same objectives, so they're all working to the same 



goal.  



      Which course he goes up on, what the sea state 



is what the environmental conditions are -- the more 



he can disseminate that information, the more 



proficiently the team will work.  If you let your 



operators work in isolation, you won't have a 



coordinated product.  It's a team dynamics up there, 



it's a team process. 



                RADM SULLIVAN:   You mentioned 



teamwork or these contact solutions are a team 



process.  When I think of -- I will ask you, the 



TMA -- oftentimes in our very high tech world we tend 



to think of things as digits, or here is the answer 



displayed.  What is your -- if you would describe 



what TMA is, in your learned opinion --  is it more 



an exact science or what is it? 



                THE WITNESS:   It's really -- it's 



really -- it's not an exact science.  Every 



parameter, when you start out, as I said, said 



several times, I think it's integrative process when 



you first get a contact, you know very little about 


Page                                                 14


it.  You start with a guesstimate of what the range 



may be based on the sound.  You start with a closing 



solution.  You may have an idea, it sounds like a 



merchant, and you start with that kind of speed.  And 



right now, your uncertainty regarding that contact is 



fairly large.  



      And although the solution presented there shows 



a discrete bearing, course, speed, and range, there 



is also an uncertainty associated with each of those 



parameters.  And the TMA process is specifically 



designed to start to reduce those uncertainties to a 



tighter and tighter value, closer and closer to 



accuracy. 



      And the officer of the deck, you know, that is 



part of his job.  It's part of the fire controlman's 



job was the accuracy of this solution.  There are 



actual procedures in the operation of the fire 



control system to provide discrete estimates of the 



accuracy of each of those parameters.  It's called 



sensitivity analysis, and the way you do it is you 



just pull all the parameters the same, and you vary 



course, and you how far you can vary course, and the 



solution fits or doesn't fit, and you get an 



estimation of how sensitive the solution is, how 



accurate it is to course, speed, and rate -- each of 


Page                                                 15


the parameters. 



                RADM SULLIVAN:   I know your tactical 



expertise, and you certainly make this to be a fairly 



straightforward simple process.  Sometimes I have to 



play out of my own mind, and I thought for years 



myself, where you get where it's more art than 



science, a lot of it is just experience, but for a 



typical submarine crew that doesn't have someone of 



your caliber or someone -- myself who is in command 



for about five years -- for a typical, what's on the 



ship, would they have the expertise you are talking 



about?  Is this a graduate level?  Or is this what 



you consider normal TMA knowledge on the ship? 



                THE WITNESS:   What we're discussing 



here is -- I think -- is normal TMA knowledge.  



      I mean, there are -- in an officer of the 



deck's maturation, he may start out with some, you 



know, some basic skills.  He may -- he will get 



better over time.  



      In other words, he will start recognizing 



indications of how to drive the boat optimally -- 



some indications of what are the best what may be 



happening with the contact, he may be more proficient 



in his mental analysis so things will be more 



efficient.  But before an officer of the deck is 


Page                                                 16


qualified, they have a base line knowledge of how to 



do target.  This is a center piece of basic submarine 



school, and a pipeline training for the sonar man and 



the fire control man.  



      And so I think there is a fundamental level, 



and as he becomes more experienced and moves up the 



line, certainly before you know a prospective XO 



school and a prospective CO school, these principles 



are emphasized again and again, and clearly people 



become more experienced and more able to do analysis 



quicker in their head, and sort of recognize what are 



the best courses to steer, and how do I solve the 



solution faster, but basically, to qualify as officer 



of the deck on a submarine, you have to be somewhat 



proficient at doing this type of analysis. 



                RADM SULLIVAN:   Thank you.



Q     (By Capt MacDonald)   Captain, I want to refer 



you again to the time range chart on the right-hand 



side of this slide, and we were talking earlier about 



the commanding officer and the officer of the deck 



having a responsibility to check all the different 



sensors that they have in the control.  



      But for all we know, the commanding officer and 



the OD did check this fire control solution, and if 



they did, it was telling them that they had a contact 


Page                                                 17


at 15,000 yards, and one that was opening.  Isn't 



that right? 



A     That would be correct.  Except as I pointed 



out, the fire control operator obviously came to 



conclusion based on -- on this -- this leg right 



here, these dots that came up after time 1331, 1332 



coming right down this line.  Right in this area, 



depending on when they looked this dot here would 



have forced this solution to not fit anymore.  



      So if they looked at what I am talking about 



the "mate display" which was presented to the court 



over at the training center, they would have seen the 



bearing dots not matching up with the projected 



solution and that that solution presented there was 



no longer accurate. 



Q     I think this is kind of critical.  



      So if the AVSDU was working, they would have 



seen this in the control room, and that would not 



have correlated with the picture they were getting if 



they were looking to the right to starboard in the 



control room at the fire control display?



A     Let me explain this better.  



      If the AVSDU is working I would expect most -- 



most ships, the captain and the officer of the deck 



would probably be focused on the AVSDU during this 


Page                                                 18


maneuver, and they would have seen probably seen some 



of this right bearing drift right there on their 



screen and said oops.  That is an alert that contact 



looks close and they would have then gone into 



further -- over to the starboard side and delved into 



the fire control system to resolve that situation. 



      But with the AVSDU out, they certainly had an 



obligation to get this information.  It would have 



been presented on one of the screens up is the time 



bearing display on the fire control system which 



would have shown this same bearing drifts to the 



right, and if mate was displayed, if you looked at 



this mate display, the bearing difference dots would 



no longer have been zero'ed, they would have been 



going off, and they would no longer be straight, 



indicating that the solution -- this solution -- was 



inaccurate.  And it would have again set-off the same 



alert that we need to develop into this contact 



further.



      If they would have looked at the parameters and 



not looked at the accuracy of that solution, if they 



looked at 024, 15,000 yards, speed 11, and not looked 



at any of the supporting evidence, they would have 



come to the wrong conclusion.  But in my mind, they 



are obligated to look at the supporting evidence. 


Page                                                 19


                VADM NATHMAN:   Captain, a follow-up 



question.  There's been a lot of scrutiny on the fire 



control technician of the watche's data, and the 



importance of that data particularly at time I think 



1333, 1334, 1335.  But what you just described to me 



tells me that one of the key issues out there was 



this right bearing drift, so it seems to me we should 



be placing a lot of scrutiny on the sonar supervisor, 



we should be placing a lot of scrutiny on the members 



of the watch team that were working the sonar, the 



displays. 



                THE WITNESS:   Sir. 



                VADM NATHMAN:   And we should be 



putting scrutiny on the executive officer who 



apparently was in and out of sonar at that time, and 



I assume -- I assume -- based on what you've just 



told me now, that here is a officer that is qualified 



as a submariner for some years, understands the 



importance of what they are about to go do, is 



adjacent to the displays that will allow him to 



understand that there is something else here that 



we've got to pay attention to, and that there is an 



expectation is, what I just heard from you, that he 



would be doing that.  



      There is also an expectation by any officer on 


Page                                                 20


the CONN whether it's the officer of the deck or the 



CO who were both acting in the capacity I think of 



conning the ship, without specifically the officer of 



the deck, I assume, had the conn as well as the 



officer of the deck.  The CO was acting in a capacity 



that I would expect a CO would have acted, but they 



both had the responsibility to pursue this 



situation.  



      It seems to me this information -- any of these 



things -- whether it was the right drift or this one 



range solution -- seems to me like this disburses 



this requirement to go look at these people, and it 



doesn't bore down on one particular watchstander with 



the range information?



A     Sir, I would like to go into that further.  



      I have some other slides to discuss this, but 



contributing to the problem here -- I agree with you, 



sir, under normal condition, you would expect the 



sonar team to be engaged looking at -- when the 



officer of the deck passes the word on the MC 



circuit, announcing circuit, make preparations to go 



to periscope depth, the submariner's mind switches.  



We now go into contact analysis and focus.



                VADM NATHMAN:   Your threshold and 



sensitivity -- 


Page                                                 21


                THE WITNESS:   --  Just goes up.  



Exactly right.  You are trying to establish a safe 



envelope around the ship to say there are no contacts 



that are threatening the ship for collision, and that 



goes across this entire team, from sonar to fire 



control, the officer of the deck -- everybody 



switches most from normal steaming mode to an 



approach to the interface, and everybody goes into 



another mode of operation. 



      In the scrutiny of looking at the sonar, and 



the sonar displays, and what was available, now what 



comes into play is the way the ship is driven to give 



the sonar men the opportunity to see enough data  



there to draw a conclusion from what they are 



seeing.  Remember, the sonar has no overt analysis 



equipment in sonar to do target motion analysis.      



      They are looking for hints that might fill-in 



pieces of the puzzle.  They may come up with a range, 



they may come up with a speed, but there is no direct 



analysis equipment that gives them Course B, bearing 



and range.  They are doing their assessment primarily 



on mental analysis and training. 



      And if they see an indication of a close 



contact, they are trained to recognize that.  They 



are obligated to call that out and say, I think this 


Page                                                 22


contact is close, but is there enough data there on 



the screen to make that conclusion.  And that's 



really a question that needs to be fully explored, I 



think. 



                VADM NATHMAN:   But to make a 



conclusion, that could be one, or here is parts of 



the data -- bearing, speed, you know, that goes along 



with TMA or to make the analysis that this guy could 



be a problem -- to me, those are slightly different 



thresholds.  



      One is a clear indication, that I know exactly 



-- I've got a piece, I can describe this contact very 



accurately.  The other one is that I think we are 



about to do a periscope depth, my threshold has just 



been raised -- I want to describe this accurately to 



understand -- but does that indicate there is another 



threshold out there that we ought to be sensitive to 



contacts that may be near, is that what we do?



A     Absolutely, absolutely.  



      They are listening to those ships and trying to 



find any contacts of where these ships may be close 



and threatening.



                RADM SULLIVAN:   Just to close that 



down.  I listen to what you are saying, again playing 



this against my own experience.  When you decide you 


Page                                                 23


have a relatively good feel for contact, and 



certainly, you don't have to have a perfect solution 



to go to periscope depth, but you have to have one 



you feel confident you are safe -- what do you rely 



on to make that?  Is it a single piece of data, one 



display -- or what is it? 



                THE WITNESS:   No, it's -- it's an 



assessment, it's the overall -- overall data.  



      It's the entire picture.  You look at the 



multiple legs.  When I talk about a leg, I am talking 



about an easy way to describe that, is the submarine 



is more or less obligated to look at every contact 



from two different views, each being called a leg.  



That's a leg of data.  



      One batch of data with one setup, one view of 



the contact, and then they are obligated to change 



that view to resolve the contacts. 



      So you are trying to look over the multiple 



leg, you may have more than two, you may have three 



or four legs on a contact.  You are looking at the 



overall picture, over time, and that's where these 



long time history displays are helpful in that 



regard.  You look over the entire period that you 



have contact on a target to try to make sense of 



what's happening, and you look at the sonar display, 


Page                                                 24


and you look at the fire control solution and say, is 



that reasonable, does that make sense with my own 



mental analysis?  You are trying to engage all 



capabilities here -- your mental and machine -- to 



come up with an answer that convinces you that it's 



safe to go to periscope depth.  



      It may not be as you stated, an absolutely 



accurate solution, but you have enough data to say, 



well, he's at least this many thousand yards away, 



and he's on this type of aspect, he's opening, or 



we're going in the opposite direction, and there is 



no way this contact is going to close in on me before 



I get up to periscope depth and can observe the 



contact visually. 



                RADM SULLIVAN:   So I've heard you 



say "integration time" a number of times this 



morning.  And to me, even the guidance that is in the 



NWPs, and it is guidance, direction from the 



commanding officer standing orders, there are things 



about time -- approximately three minutes, 



approximately, whatever. 



      That seems to be -- I ask for your opinion -- a 



key -- the guidance as to why you do this type of 



integration, to get a solution that you have some 



validity in?


Page                                                 25


A     That's correct. 



                RADM SULLIVAN:   And why you need 



that time, you need a couple of things really to help 



the process.  The machine, for instance, will take 



out own ship's components of the relative motion 



plot.  And it can analyze through the fact that my 



ship is still maneuvering or changing speed and will 



take out the -- because it's fast, and it can take 



out in its processing the effects of own ship's 



maneuvers.  But the human brain is not as fascile to 



do that.  And so, to do a mental analysis, you really 



optimally would like to be on a steady course and a 



steady speed to observe the contacts bearing, drift, 



and to look at -- to assess what the real bearing 



rate change is on that particular look, you would 



like it to be steady, and you want enough data there 



that you are not subjected to bad tracker data.  



      I mentioned that yesterday, the tracker 



sometimes -- it's a -- it's a mechanical device, it's 



a machine -- it can track off a little bit.  



      You want to have enough data to have confidence 



that the data is consistent and reliable, and that 



all takes a certain amount of time.  You need to get 



the ship steady, you need to have enough integration 



time to let the contact situation develop, so that 


Page                                                 26


you can make a proper assessment mentally to compare 



it to what the machine is coming up with, and to come 



to common agreement that we have an estimation of 



where this contact is. 



      If you try to compress the time too much, then 



you start losing accuracy.  And you can make -- make 



an improper conclusion.
