I saw a formula to calculate this related problem and found that we should technically be able to at 120psi, with a 3/4" x 10" cylinder, have 20 actions. What am I doing wrong?
I believe your calculations are shown by your experience. The 20 "actions" you calculated theoretically transfers to the actual 18 you got, 9 ins and 9 outs, if I'm understanding you correctly.
