1. Directly from my posterior. Yes, 1.6 ATA is the most accepted limit,
yes
the NOAA guidelines have times associated with each ppO2, yes I have
heard
1.4 going around recently.
2. Air looks pretty good to me in the 0 to 60 fsw range, in the range of
exposure times reachable with today's open circuit scuba equipment.
I can understand the argument that the default gas pumped should be
EAN 32,
so that all recreational diving is done on "SafeAir".
3. I will immediately start over with a new attitude.
