My point exactly!!! I want to know why people choose to take that risk.
I trust that Wookie knows Wookie.

1.4 max bottom, 1.2 planned bottom for deeper dives, 1.6 for deco.
Now you cut it out, too! You haven't told us about why you punch up the PPO2! :scorned:

Aren't you curious why people would do something? I like to know how a race motorcycle rider countersteers through the turns . . . . I don't want to run out and try it.

On flat track they use weight and throttle, on motocross they use weight, muscle, throttle and brakes. On sport bikes its weight, throttle and their knee

I think they do it because they have inappropriate exposure protection to do the deco they signed up for. so they push ppo2 on the bottom to reduce it, instead of spending money on equipment. Or they'll dive air deep to save money on helium. relying on nitrogen being a CNS depressant to stave off a toxic event on the bottom.
or some of them just want to see what will happen. it doesn't much matter to me.
the problem being, Johnny Scubaboard comes along and sees the people doing this have tons of technical training listed in their profile or they're an instructor, and people on here say oh that's so-and-so he has tons of dives so he must know what he's doing. then johnny goes out to some deep wreck or eagle's nest and bites it.
there is a reason the max acceptable ppo2 has been scaled back. it's not just for $h!ts and giggles

And how many bones have you broken? :blinking::focus:
As mentioned before, the Navy used to find a max PPO2 of 2.0 acceptable. In the past 10-15 years, they've dialed it back to a max of 1.6.
So -- I'm asking for a SWAG here -- What kind of percentage of injury /death is acceptable?
If a max PPO2 resulted in 1% deaths and 3% incidences of OxTox . . . (that's a made-up statistic!) say, over a year.
And now the max PPO2 = 1.6 is resulting in .1% deaths and 1% incidences over a year . . .
What's acceptable?

I agree with the last part; with some digging, I could find it.
But for the first part . . . . when are we going to stop being responsible for every stupid Tom, Dick, and Harry? Shall we all do like the auto industry's "Closed course, professional driver, do not attempt", and put "Personal decision for this diver, do not attempt" in our sig blocks?
You can try to make things fool proof, but a better fool will come along.
