- I'm a Fish!
the dil doesn't really bother me, but I'm a cave diver, so there's that. I usually shoot for 1.0 bottom dil ppO2 for cell validation, but close enough given the circumstances, I certainly wouldn't call a dive because of that, though I would probably have asked for a bit more He due to the END.
Bottom ppO2 is a lot higher than I normally like to run though, even with the rich dil, it comes down but that's personal preference.
Descent rate looks fine for OW at about 60fpm, nbd there and ppO2 was stable which is what matters.
The last few mins at low ppO2 is weird to me but you were already fully cleaned out.
Strange stop depths though but to each his own there, though depth stability looks a little rough, but who's to say what the surge was like.
your comment on flaw 2 for ascent rate is what it is. 17fpm is a lot better than 70fpm, certainly not what I would call a cockup, especially on a CCR.
Flaw #3 I would actually call out as no air breaks instead of letting the ppO2 drop. Your sinus's like the air breaks which helps with deco efficiency to boot.
The 1.6 check I do, and is especially important if you're running a 1.3/4 for setpoint. I usually run a 1.0/1.1 so it isn't really critical on descent since I'm running at the level that I calibrated with. If I'm going to run a high setpoint on deco, at least before 20ft, then I will do it on the way down since I need to know that they aren't limited before I get back to 20ft. If my only plan to use setpoints higher than what the bottom dil would be is on the 20ft stop with O2 then it doesn't really matter. In this dive I would certainly have checked for limiting at 20ft before I got to the bottom and flushed. I try to splash with a loop full of O2 on every dive to not only handle that but there has also been some research done that says it helps the tissues to have that hit of O2 before you start diving.
