Adam, As mentioned, *IMHO*, the bail-out gases weren't the best choices, the deco profile seems a bit excessive and there was really no alternative bail-out deco profile to get out of the water ASAP. Thus this whole discussion is a moot point, so let's not continue... But to answer your question, the amount was barely adequate with very little reserve if you calculate with the parameters mentioned. -Phi http://oxycheq.com/DecoWeenie.html http://groups.yahoo.com/group/PalmPlanner (Program/Manual in the "Files" section) -----Original Message----- From: Adam Volosik Dear Phi, I understand your point however, doesn't the low PPO2 of the 10/50 mix cause problems with the deco? The other question I've been mulling over is the 80 ft3 of gas enough of a bail out? It seems to me they didn't leave enough room for error? I now you guys know way more about rebreathers than me, I should probally keep my mouth shut before I get into trouble but the whole description of the dive just me wonder WHY?
