"It's not difficult to tune your computer to your body; just get bent and then increase conservatism"?

I didn't want to say that. But adjusting a dive computer settings is making a guess about a program, rather than "tuning the computer to your body". At best you could claim to be adjusting a program to accomodate how you think your body is functioning on any particular day, but that is a very subjective assumption.

I think you are misinterpreting my comment. Tuning does not mean changing your computer setting randomly before each dive, but rather adjusting it in what you think is a useful direction, based on how you feel after many of your dives. Suppose you are doing NDL diving with a GF-hi of 95, because you like long dives. But you've also noticed that now and then, perhaps on the third dive of the day you surface with an aching shoulder and an itchy chest. Maybe GF-hi 95 is too aggressive. Drop back to 85 and see if that helps. If it does, maybe bump it back up to 90 and s÷ if that is still ok. And you need many dives to sort this out.

The only way anybody could actually “tune” their body to their computer would be if someday there was an inline blood sensing computer that was actually hooked up to your vein/ blood flow and the blood went through the computer with sensors.
The other way would be to go for a multi situational chamber ride with real time blood analysis happening, then based on that data an algorithm could be written for your body specifically.
But both are pretty far fetched so in the meanwhile we just keep diving under accepted general alorithms.
One day you could be diving just fine, the next day you get bent with no warning whatsoever.
Just stay in shape and don’t abuse the science.
In most cases they are a lot smarter than you are.

If you get bent to where you get skin bends on your chest and an achy shoulder, that’s going to be a chamber ride. Then it might mean some time off from diving until you’re cleared. If you’re bent enough to show symptoms then you’re already way past any safety zone. That means micro bubbles have maxed out and they’re now forming larger bubbles that are causing visible and neurological distress.
You’re not going to just drop back to 85 and go back in!! lol!

You and some others speak of DCS as an all-or-nothing event, and somewhat random. Nonsense. There is fatigue, skin bends joint pains....lots of little things people tend to ignore. Not all DCS is a crushing event, frothing at the mouth, full-body debilitating. The key is to listen to your body and build a bit more conservatism into your profile if you feel the "nigglles."

So you are saying there is no point in having adjustable GFs, because you don't have complete knowledge of your body. Right.

I think you’re wrong. And I never said DCS was an all or nothing event. There are many stages and variants of DCS, some of it can be silent and the person may not even know anything is going on, some of it can manifest as a little fatigue to more fatigue and brain fog.
But If somebody gets skin bends and aching joints that’s is already significant enough to warrant an eval and possible hyperbaric treatment.
I’m very surprised somebody like you would minimize this and suggest to just lower the gradient factor and keep going. I think that’s pretty irresponsible.

I'd stop diving altogether if I'm feeling these things.

i agree, that's irresponsible, which is why I did not suggest that. Sure, treat the skin bends or joint pain as one should.....but then how do you adjust your GFs for the NEXT time you go diving? You lower them, right?

You wrote this ^^^^^
I don’t see anything about stopping diving, getting on O2 and calling DAN.
You mention dropping back to 85 and trying again.
Then you say if it seems ok to bump it back up to 99 and see if it’s still OK.
Are you nuts??
