Here is the data for a typical dive I did three weeks ago on Roatan:
7/5/2010 Roatan 77.4 3000 65.3 2988 1363 26 84 0.33 0.359
Cyl: AL80
Cap (Cu Ft): 77.4
Rated Pressure (psi): 3,000
Dive Time (min): 65.3
Start Pressure (psi): 2988
End Pressure (psi): 1363
Avg Depth (fsw): 26
Min Temp (F): 84
My SAC calculation: 0.359
SAC = {(77.4 x (2988-1363)/3000)/65.3}/{1+(26/33)}
Suunto's SAC calculation (corrected to STP): 0.33
