Please let Simon talk... He was just about to get to the big point he spent a while building up to, "The question is, where should we putting that deepest stop....." ..... But then Ben interrupts... 12:50 .... over the next 6 and a half minutes, Simon's face then slips into slight despair... Luckily Jeff saves it at 19:20 and brings him back to his point. Great series. Simon is always such an interesting speaker and educator. Get him back again! There's never enough dive science lectures online!
Absolute appreciation for you guys sharing this content. I'm not even tech certified yet however very aware of the topics discussed at hand. Great respect for the candid open discussion provided on these topics. Very dynamic discipline and area of study. 🤙 Cheers, #SeattleRingHunter
Isn't the fundamental issue the fact that there is no simple practical method for determining the DCS margin on any given dive by any given person under any given environmental condition? Ie if your decompression planning is conserative enough to always keep one away from any noticeable symptoms of DCS, then how do you rate that conservatism? Realistically, studies these days have to have a sufficiently low level of overall risk to enable them to be carried out (the days of simply exposing some of your soldiers to some nerve gas and seeing what happens are, thankfully, long gone) and so the true "Limit condition" is not accurately known with any statistical confidence. The mathematicaly models used for Decompression are just a way of repeatibly creating a reference curve, in effect a "this was fine last time, so it should be fine now" kind of situation. "How" fine it was, on any given dive, i'm not sure we know? So to me, it seems what needs to be developed is not another mathematical model, or tweaks to existing ones, but a definite way of establish the margin to DCS under any given situation? That i suspect is really quite difficult indeed, and particularly in such a relatively niche activity as deep diving, where the number of potential study subjects is very low, meaning statistical confidence is difficult to establish?

It is always a pleasure listing to Prof. Mitchell. Thank you for the interview.
A super good and informative podcast. Make sure to watch all 3 parts.
These UDI guys just won't let it go will they.
How interesting, great discussion ..loved it ..
