    Efficiency calculator

    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?

    Hehehe....I made that "pockets" comment on an American-dominated forum the other day, and I got the impression that a few of them actually believed we had pockets in our underwear!

    Once I wiped the tears from my eyes from laughing, I explained that it's just a saying like "greatest thing since sliced bread", but I don't think everyone was totally convinced...

    Too funny!
