There are two things that affect a shot the release angle and the release velocity
Ways to change shot:
Firing different number of Pistons
Pulsing pistons(artificial hard stop)
Adjustable hard stop

And the PSI, but yeah, basically sums up the ways I've seen.

You should look at a close up of our 2014 catapult. We had a pair of fingers that we could change the length of in order to adjust the shot(release angle) and a deployable hard stop to change the release point(release velocity). Ours was powered by a bundle of surgical tubing and drawn back via a cam.
