Great point, it is just wrong.  Maybe for typical RB exposures, which
probably don't really require deco anyway, but not for serious exposures
like those encountered in long range mixed gas cave exploration dives,
a.k.a., the WKPP.  Our lungs just can't take the beating, and if you lower
the PPo2 to a point where we can, well then what is the point?  Pete, if
you had done any of these dives, you would know this.  Your math goes right
out the window when your chest hurts every time you take a deep breath. It
is just THAT simple.

Been there, done that, learned better,
Trout
