In other words, she could easily have taken him to the surface, even with
this bullshit schedule.

Hi guys.

For all the conspiracy theorists out there, this is what the profile looks
like at a 1.3 set point and zero conservatism. Please note the deco time.
Remember the decent time was 15 mins which alters the gas loading VERY
considerably.

Here's the gas change to 10/50 for OC bailout at the end of the bottom
interval. Discount the 1 minute I've added as anyone aware of the situation
would be headed for the surface already.

Total OC gas required is 90cu/ft of 10/50 and 28cu/ft of O2. This is
absolutely worst case as it presupposes 6 minutes of bottom time at 300
instead of the 5 planned after the slow descent, and it also presupposes
that the 1.3 set point was not maintained on bottom.

Feel free to pick holes... I'm not presenting these numbers as something I
would personally run, but they are certainly representative of current deco
program output.

Hey Art, think about this, it was mentioned I think twice in the report
about a bailout plan. How do you bail out of a 300' CCR dive while only
carrying (1) Al 80 w/ 10/50 and (1) Al 40 w/ O2? If the rebreather was
mal-functioning how do you decompress with those gases on open circuit?
