At 102 feet? ... it's just from a long-ago PADI training and a couple of shallow dives following, but from what I remember:
- the rule of thumb is that 30 feet of water get you an atmosphere. So you're at 102 you're at just under 4.5, so you're using air at the rate of 4.5 times the rate you do on the surface.
It's 1 atmosphere for every 33 feet, but either way, I don't see how you managed to get 4.5 * the rate. At around 3 atmospheres, you're using air at about 4 times the 1 atmosphere rate.
- My dives were usually 30-60 feet (say, half the pressure the H.E.A.T. team dealt with), and I was able to stay down for over an hour, with one tank. That means that with two tanks they should have had at least a similar limit, say an hour. On the other hand, I wasn't wrestling... Exertion can pull you way down. If they were giving a definite, solid time limit, it's definitely bogus ("Let's see, five minutes at 10 times air consumption while you fight...") for air limitations.
Hmmm. I believe that the diving depth-to-time tables (which I don't have in front of me. I'll get them out and double check later) give a time of around 25 minutes. It has nothing to do with how much air you have. The tables are used to avoid the bends and nitrogen narcosis.

That's because you didn't add the 1 atmosphere you've already got above the water to your pressure count, while I did. We clearly meant the same thing, since we both got ~4 times the rate.

I've been assuming that it wouldn't be a problem for the H.E.A.T. folks to ascend slowly. Wouldn't this avoid decompression sickness? Again, it's been a really long time -- moving from Florida to Pittsburgh and then NYC will do that. -- L.
