From what I could determine, I was getting 3 pods (and a little change) using 1500-1700psi off of a Ninja 68/45K W/Dye Throttle Bottle -- so if you do a little rough calculation, I could probably get around 7-8 1/2 pods with about 4300psi (never 4500psi, because the field system can't reach it), which equates to oh let's say..1000+ shots?
I was shooting a pretty constant FPS of about 275 (+/-7), with a paint-to-bore match of .690/.691 using Empire All Star in conjunction to a Proto 2-Piece 11" Barrel. Nevertheless, I definitely know that you can get more efficiency with the proper Oring fitment. The stock bolt assembly Orings are so ridiculously poor fitting that more air/pressure is needed to actuate the bolt than necessary
Hope this helps,
