Yes, I was going by what was said in the manual as well. And the 16 figure is on Clippard's website as well, so I can only assume it's closer to being correct. So I went with the 16 figure and didn't bother with a calculator. I just estimated it out. Yes, figuring that 32in^3 at 120 PSI is effectively 64in^3 at 60 PSI minus the 32 that must be left in the tanks. so 1 cycle of extend retract. or 2 shots by your counting method. I whipped out a calculator later and 45psi seemed about right for 4 shots.
