I use subsurface to download my dives. My computer is AI, so after selecting the tank it will give a "sac" rate. For example on a recent dive using an al80 it shows for a 63 minute dive i used 51.23cuft of air and had a sac of 0.39 cuftmin. Max depth 96 ft.
Is there way to get psi per minute from subsurface? From my understanding the cuftmin is really the rmv, not sac. I see hand calcs for going from a psimin sac to rmv but not the other way around. I'm sure I could use the same formula and solve for the psi, but my curiosity for trend analysis does not extend that far.
