Bill,

For those of us who have been to D tunnel many times it came as a huge =
surprise to find that it takes over 50 minutes to get to the socalled =
"Scooter breakdown room". (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
