Brett said it was in a chamber and the diver had exceeded his CNS clock.
That's certainly not clear from the context of the US Navy Divers Handbook
warning. We (I) need more data, even if it's anecdotal. I also have a lead
on some folks in Germany and a Prof Elliot in London. I will try to
contact them and see if I can get some empiric evidence. I feel
uncomfortable relying only on opinions for something that could be fatal.
What do you techdivers out there actually do? Commonly exceed 1.4 ATA
while excercising? This might be at least some collective experience.

Thanks,

Peter Heseltine
