    84 - 48 = 36ltrs used
    55/36 = .654
    so 654cc's per shot .25 at 42ftlb
    or there abouts.

    .177 is least economic with air, .25 most economic.
    Is your gun regulated or not? I'm guessing it is.
    I've read a rule before of about 1cc to 0.5cc of air consumption per ft/lbs in a regulated gun so that must be wrong?
    Edit:that is plenum volume not air.
