dumpsterDiver:So how much does oxygen speed up deco compared to air? Is there a somewhat universally accepted figure for the increased offgasing rate? I sometimes use oxygen to help on deco, but to be honest, I'm not sure how much of a benefit I'm getting.
Last weekend I did 15 minutes on air at an average depth of around 200 (max 210) and my Oceanic hockey puck computer kept adding deco on the deep stops and I ended up with over 50 minutes of required deco. I usually bring some oxygen for part of the deco, but I'm really curious if there is a rule of thumb for oxygen. Could it be 5 times faster, because the N2 gradient is 5 times as high?
Doc Intrepid:very few of us could constructively critique Bruce Weinke's mathematics regarding (or even understand the math published in his Deco Primer),
lamont:I've tried going through Weinke's _RGBM in depth_ book, and the math appeared to be incomplete. Its a mathematical sketch of what RGBM looks like, but I don't think there are sufficient details in there to implement it.
If someone has implemented it from the descriptions that Weinke has published, I'd love to talk to them about it...
Rec Diver:Haladine is not outdated. Most of the computers manufactured today are based on the Haladine tables, check your computer specs. The Navy tables haven't changed in the last twenty years. Even with all the continued testing they have stood the test of time. So what are you afraid of? Use your tables, or computer, and dive the way you want. My point was that Geoerg Irvine and the DIR group did not invent scuba diving, or decompression diving for that matter.

lamont:And I believe that US Navy is looking at updating their own tables with ones generated from bubble models because they've recognized that the existing tables are out of date.
