IMO the #1 tip to shooting consistently regardless of ones individual form is the proper use of back tension and shooting a relaxed shot.
Punching the trigger and anticipating exactly when the release will go off will kill accuracy quick fast and in a hurry.

You can do a quick little check to see if you are using back tension at all by seeing what happens to your release hand at the shot. If your release hand never moves when the shot is fired and just sits right at your anchor you aren't shooting with back tension.
The condensed version......don't grip the grip, bow arm is resistance only,good repeatable anchor, draw arm in line with path of the arrow, relax both hands, fire the release at least in part with back tension.
Provided the bow fits to begin with. Its very difficult to do the right things if the equipment you are using is counterproductive to doing them in the first place.
