The thing that helped me most while at the academy was this: focus on your sight picture. No matter what I was doing otherwise, or how I was moving, I kept thinking to myself "keep sight picture". I focused on making sure my sights stayed on target that everything else took care of itself. On just the moving portion of our training, I hit 48/48 (on the body of the BG on the target). I don't know if that will help you, but it certainly did me.
Truth knows no political correctness.
I do not aim with my hand.......
