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.

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.

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?
