Shoot and then shoot and then shoot some more. At least a few days at 'minimum DW'.
While I agree with just about everything written on this post so far, I couldn't disagree with this more. Remember practice doesn't make perfect. Perfect practice makes perfect! You need to work on aiming, not on shooting. Draw and hold on the target without firing. The best way to do this is to have a release that you can lock the sear on so that it can't fire. That way you can go through your full shot sequence without firing: address the target, focus/aquire the target (envision where the arrow will strike), draw, anchor, sight focus, aim, start the back tension, aim, aim, aim (for about as long as it usually takes for the release to fire) and then let down. (This is of course assuming that you have a solid shot sequence and release down first, don't put the cart before the horse.)
