We very easily could deco out on back gas. The only thing the 50% does is accelerate the off gasing process..
In fact, if you compare your gas ( ie; 79% Nitrogen) versus our back gas ( ie 55% Nitrogen ) you can easily see on a strict comparative basis you are uptaking N2 at a much greater rate than we are.
As to the dive itself, we ALWAYS run a continuos line from the anchoe line, using a secondary tie off, and then run a reel the whole dive.. There is very little chance of us not getting back to the anchor line. Should that ever happen we would shoot a bag and do a floating deco..
