We've been doing a lot of calculations ourselves. We aren't going with a shooter/flinger though, so different design considerations. It seems with your configuration you could do a full extend/retract cycle before your working pressure begins to seriously decrease. I'm sure you and a lot of other teams have already figured this out, but it seems like if you are using a cylinder to shoot with, you can't get enough spead on the ram to move the ball very far, no matter how big a cylinder you use. The tubing we have to use limits the mass air flow such that the cylinders can't move very fast. I suppose with the creative use of levers, a speed magnification can be achieved, but with a loss of force. Bah, we're just going to lift and drop.
