Your Gradient Factors?

[PfcAJ]

I could tell you but since it almost killed me, I won't

Better keep it a secret so that way no one else does it.

I dive 50/85

Probably 5000 dives on ~90 , maybe more. Whatever Orca used on EDGEs, Skinny Dippers and Marathons. Probably get a Shearwater one day just to see.

My thought - it's your surface gradient factor that matters.

With your profiles, it would be interesting to see and maybe a good measure for you.

Get a SW, you would like it and it would be good for you.

No idea... I just like to Polaris missile myself from 6m onto the swim grid once my average depth hits 21m again.... DM’s dig it!

20+ years ago several prominent tech divers in Germany were diving a GFhigh of 150. I tried it too for less than a year, It worked but I was extremely tired after such dives. Dropped my GFhigh down to 125 and that worked well until about 2008. Similar problems then and I dropped my GFhigh down to 100.
6 or 7 years later I was having issues with a GFhigh of 100 on multiday trips involving 2 Trimix dives a day after 4+ days.
Now I'm older, use a GFhigh of 85, and take a 1/2 day break after 3 and a half days of doing 2 trimix dives a day.
It works for me, cannot say that it would work for you and if you get badly bent, it'll be your own fault.

That's fascinating, and insane. Never heard of intentional GFs >100. Courting disaster.

Tiredness as a common symptom of decompression stress is also really interesting, wish there was a better way to quantify that or some understanding of the mechanism. Hard to know when it's "deco" exhaustion vs. regular exhaustion from diving, gear handling, getting up early, etc. at least with minor normal exposures.

That's also insane, and hard to tell if you're serious or not.

Has to be an attempt at humour, right?

It depends on the dive. Paradoxically, the shorter the decompression obligation, the lower GF-Hi I prefer. Example, a ~60 minute swim at 90' average depth, I'll probably run the equivalent of a GF-75 or 80. A dive with a six-hour decompression obligation I'll probably run equivalent of a GF-90 once I get to the shallower stops.

Why is that Kensuf

 

[Graeme Fraser]

I run 80, which my body seems happy enough with. No particular interest in pushing my physiological boundaries to discover where the actual red line is, especially as I'm not getting any younger.

More often than not I'm surfacing on 75 or less.

 

[DiveTucson]

99/99 why run anything else
