I know Bob posted this info/formula several times, but I can't seem to find it for the life of me (should of bookmarked it...or at least paid more attention )

Does this sound about right?: Total fpe (fpe/shot X #shots) divided by total ci of air used (bar used X ci)

Example (using 13 ci bottle):

31 fpe/shot X 40 shots = 1240 fpe divided by 1345.5 (103.5 bar used (1500psi) X 13 ci = 1345.5) = .922 fpe/ci

I probably made that more complicated than needed, but........yes, no, maybe?
