Take enough time to get an A hit on the first shot of an array entering a shooting position and the last shot on the array before leaving. Stay in the present instead of thinking ahead to the next target.
Try sticking a 6 x 6 piece of white paper on the 25 yard target and tryaiming at that. Having a more precise area to aim at may help you get started with your accuracy quest.
Also as ChaLee said earlier, shoot a minimun of 2 shots for As on the draw in live fire. You can cheat on control a little if you only go for one shot, not so much with two
