I am not familiar with this. Please post a link that at least identifies who is doing this talking.

The figure in my previous post is from the RF4 proceedings:

I think I heard it reported that one of the recent Harris deep dives also encountered realities of 'normal' GFs for typical trimix dives (≤100m) not necessarily being failsafe for dives deeper than that (?)

So iso-risk questions for exploratory deep diving is trending

Hi everyone, in your trimix dives, which gradient factors do you use with the Buhlmann model?

50/80.

50/75 if I am in an urban-ish area close to medical attention. 50/70 or 50/70+ a bunch of extra shallow time until my paranoia is minimal if I am remote.

Remote = days to get to a chamber. Or so far underground I'd be dead from hypothermia before you could even start to address the DCS problem.
