Subject: Gradient factor conservatism
Date: Mon, 23 Jun 2003 23:12:25 +0200
I have quite little experience with long exposure dives. Longest deco I've
been was about 40-50 minutes according to my Vyper computer (p0/a0). It was
deep dives but in warm tropical water. I had no problems with above dives.

I'm starting to dive longer and deper deco dives in much more difficult
conditions - freezing cold!!! Usually in drysuit and +4 deg celsius
temperatures. Now with PC generated tables, hot nitrox and oxygen for deco.

What should be setting for gradient factor in programs like GAP or others?
If I leave standard LO 0,20 HI 0,70 deco times are much longer than with
Vyper simulation. What should I set to get to M-value not much further than
Vyper but still have safe distance? My bodyfat is average and I'm in quite
good health.

Should I experiment with GF and watch for subclinical DCS symptoms? Sounds
risky for me.
What about GF for nitrox and trimix diving. Should I leave the same for
trimix?

TIA
