Hey Steve,
Latest I've heard, this December. I appreciate your and everyone else's comments to this thread.
With my limited knowledge of decompression and the theory thereof, I'd like to make a few comments. We know that staying at a deeper depth will require more gas. We can agree that staying at a deeper depth will increase our CNS % if the time is roughly equivalent to that of 20'/10'. So this begs the question "Does staying at 20' on O2 better facilitate decompression of inert gasses because the partial pressure is higher or does stopping at 10' accomplish the decompression better/faster because the partial pressure is decreased once the appropriate time has been spent at 20'?". I think this may be where theory comes into play, maybe not. I do know that using VPM-B, configured for salt water and conservatism +2, deco gasses EAN50 and O2, the calculations have resulted with a marginally shorter run time doing 20' & 10' versus just 20' on some of the dives I've planned. And that, gentlemen, is why I asked the question. That was a great trimix class you taught Steve, best dive course I've had to date.
