(The profile is symmetric around the 50 minute = point, so I guess this is where they turned the dive) We are talking = 2400 ft here to the end of the line in D. The disclosure of the MK5 = Rig021-121898 download profile further compounds the mystery. (see = http://www.wakulla2.org/Updates/dec18_graphs.htm). Apparently the MK5 is programmed to "lie" since it reports a max depth = of 290ft and we know that the depth just prior to the scooter breakdown = room is over 300 ft. on the ceiling. As a matter of fact, I recall a = reading of 305 ft on my depth gauge. Do you know where your dive team = actually was?=20 Why does it take nearly 20 minutes to get into the cave? What were your = boys doing, crawling? Perhaps you can get your spokesperson, Richie = (Mike McCurry) Pyle to explain to us what clever nuance in the MK5 = software caused the oxygen to spike to nearly 1.9 ppo2, 7 to 10 ten = minutes in to the dive. Then after he has finished telling us why this = is intentional and a good idea, he can tell us why it is a better idea = to spike the oxygen back up to almost the same levels after 95 minutes. = This of course, when, according to the download log, the divers were at = nearly 160 ft. There must be a very compelling reason for this or maybe = the CL was just "lying" again when it reported these values. Where is the great deco advantage to the MK5, that Richie has been = telling us all about, when you are doing over 500 minutes of deco for = what we would consider at most a 60 minute bottom time? I am sure you = remember Richie=92s two legendary, swear on a stack of bibles, 60 minute = bottom time dives to 300 ft in one day. That means Richie did 1000 = minutes of deco according to this program. Oh, wait a minute. That was a = Mk IV and it took place in another time zone. That explains the = difference. Whew! That must have been one long day.=20 Bill, if this problem persists, I think the solution would be to = incorporate a lie detection algorithm in to the Cis.=20 BTW, what has become of Jim King?=20 Regards, Bill ------=_NextPart_000_002E_01BE2CE8.A409E7E0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD W3 HTML//EN"> <HTML> <HEAD> <META content=3Dtext/html;charset=3Diso-8859-1 = http-equiv=3DContent-Type> <META content=3D'"MSHTML 4.72.3110.7"' name=3DGENERATOR> </HEAD> <BODY bgColor=3D#ffffff> <DIV> <P>Bill,</P> <P>For those of us who have been to D tunnel many times it came as a = huge=20 surprise to find that it takes over 50 minutes to get to the socalled=20 "Scooter breakdown room".
