The fact is this is again in a vacuum of variables. The real story is
that the incidence of tox drops off markedly below 1.4 Working ppo2 and
1.6 resting, and that those guidelines are subject to total exposure
over time, time it self, repets over days, spikes, stress, complex brain
chemisty issues, complex physiological variables and issues, like cold,
immersion, vacularity, persfusion, gas transfer, hormone levels, etc and
all of the potentinal variables discussed in this source a lot more
thoroughly than is suggested in the reguritation of the idiots version
of this bullshit by any of you strokes.

If you do not actually know what you are talking about with serious
issues, shut tthe fuck up - both of you, and all of you. I am real sick
of rereading the abject stupidity that is taught by the agencies and the
half asses specualtion by the antique morons at Navy, NOAA or anywhere
else where ther are no consequences.It is no acCident that the real info
comes fRom the paying customers, like Shell Oil and the WKPP, and not
from the nickelrockets elsewhere.

Real life diving is done corretly by very few interests, most of them
commerical, and a few of them like the WKPP. The abysmal level of
bullshit misinformation out there is frigthening. 

I continue to be amazed at the number of people who live rather than the
many who die diving. Luckily most peole are such pussies that they can't
get into anything that will kill them other than just straight bounce
diving on the wrong gas.

And by the way, Martin , you have no freaking clue what you are saying,
and you need to join Black in the corner with the dunce cap on.
