Fine. You're not wrong for running a lower PO2. For deep mix dives, I tend to keep my PO2's below 1.2 ata. I'm thinking not only of the potential to oxtox at depth, but on the long hang afterwards where I run PO2's as high as 1.6. Oxygen dosages are time/pressure dependent and cumulative.

Consider, however, that nitrogen is your enemy. Period. It's unfriendly to off gas from due to the adverse physiological effects it has on RBC's and the higher PN2 per unit of time, the more decompression stress you're under. True, DCI is a lot easier to recover from than a tox hit, but puublicly stating that using 36% on the Yukon is "ill-advised" is pretty presumptuous considering there is very little time spent at a PO2 above 1.4 ata (96 fsw!!!!). I have no idea why you would want to spend time in the sand on a completely intact wreck with no artifacts.
