focus on body control and forget everything else, including shot results and everything Scatt shows me.
The upper is one of my drills as a pistol shooter, however many shooters in my club are in competition up to national levels, including myself, and rifle shooters also use similar training technics.
An example for rifle shooters is to take your position, all the way from the rifle laying on it's stand to final aiming, with both eyes closed. When opening your eyes at that moment you will easily see any disalignment: if your eye is not align with your sights, if your aiming is too low or high, etc. This means that you don't have the proprioception of your correct position. Although you feel being in the correct position, you are not. The consequence is that when shooting you are always compensating for the wrong position with contractions (and you don't feel doing this compensation), which in turn affects your shots.
Following this finding, you will train correcting your position, concentrating on the feeling of the body changes, in other words correction your proprioception of the correct position.
At that point an exercise can be to take your corrected position repeatedly, and every 5 times or so, do it with your eyes closed, to check how your correction is becoming effective.
Another very efficient exercise is to have an aid surprise you in the middle of taking position by calling "close your eyes". This will help you detect if you are really using your proprioception at every shot, not only with the voluntary closed eyes shot. Extremely efficient as you can't cheat with this one.
Yet another exercise at the range is to have an aid loading/cocking your rifle, although sometimes not loading ammunition, to surprise you. This also helps detect if you, even unconsciously, don't have the same position when dry-firing as when live-firing. That happens very often.
When you think your body proprioception is well corrected, thanks to the Scatt you can also attempt a dry-fire shot with closed eyes. Kind of the ultimate test.
This series of exercises or any similar you can think of is probably efficient whatever your gun, caliber, distance, shooting position etc. It is core basic training.
