I'm sure he's gonna chop me to pieces :-/ On a dive like this, you could set GF to 20/100 and still shave about 1/3 of the 6m stop, that leaves you with 40 mins of O2, which is still too much. When I asked about a similar profile, I was told I did twice the deco I needed. Of course, this is individual, and you might not want to do the deco George does straight away :-) Start your stops deep, reduce your ascent rate to 3m/min when you reach Decoplanners "Max Stop Depth". Remember, if no bubbleseeds form, there's no chance of decompression illness! Sit on your gasshifts to make optimal use of the O2 window., Do 12-15mins on O2 to allow for a good O2 window, 6mins off to allow the vasoconstriction to recede. BTW. I think EAN32 could hit you pretty hard at 39m after the high helium contents BG. May be better to add some helium or move up a bit before changing. -- Oystein -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
