I had that same problem, and i had to jerk each shot up. My main issue was anticipating the shot. I would assume that that is your main issue, which is causing you to flinch. It was awful. However, I found if I center the pin above the target and slowly drop it down over the bullseye while squeezing the trigger, i got used to the bow going off and seeing the pin on the target. after a few repetitions of this, I was able to hold the pin on the bullseye without any trouble and squeeze the trigger on the release.
