Greg,
I'm going through it right now with great success at getting it under control. Well first i approach the target at a close distance, pick my spot, and draw to anchor, all the while telling myself..."dont shoot idiot" i do this about three times before shooting. When i can shoot the way i -should- everytime i then move back 5 feet(sometimes one step) Also when i have my wife shooting with me we take turns shooting, when it is my turn to shoot, i have her count to five, starting when i reach full draw and anchor. the rule is that i cannot shoot on 1-2 and cannot after 5, i must shoot at a natural timing while not "conciously" releasing for the shot. Anyway i have gained significant control in a short itme will doing this. Also let me add, if you sart messing up, go back to a closer range and try not to shoot over 30 minutes..Practice with a purpose... Hope that helps.
Paul.
