Deep Stops Increases DCS

It does exist. Its just not commercially available. Calibrated against controlled dives. User adjustable risk. The whole deal.

I would not jump on it, until I had a thorough understanding of the assumptions, algorithm, and conditions. All dives are "user adjustable risk", it is just that the brain does it, not some computer . . . .

Except you have no idea how much you're adjusting it.

10mins less oxygen. What does that do to your risk? Does it increases your risk by 1%? 10%? You've got no idea.

To go the other direction, 10mins more on a given profile might not reduce your risk at all.

I think you are reading "adjusting it" as adjusting the computer's settings.

Some people see a computer as a minimum recommendation. And how would know know if I have no idea . . . or understand it thoroughly?

Deco for Divers has a nice write-up for probabilistic models.

No. I'm not.

You select what chance of dcs you feel is acceptable. That chance is calibrated against real control dives.

Is there enough published information on the probabilistic models, or even the probability estimators, to support an implementation?

I believe so, but I don't know where it is.

I've read that one of the issues with the trend towards replacement of divers by RoVs and atmosphere suits for commercial and naval diving is that research funds for decompression research are very limited these days.

Ross would claim risk goes up though!
