It's important to note that the NEDU results are for depths in the 170 fsw range. As floridabob noted, dives in the 200+ ft range are another matter. I doubt there will be meaningful empirical results for such depths but there may be ways around it building on the NEDU results. For cave divers w/o trimix/AN/DP training (there appear to be some) I would encourage to read the NEDU study. It's a well-designed, sound scientifically meaningful study.
