I think it also helps instill the discipline of follow through. If you consciously decide to hold your position long enough to remember the shot, instead of trying to get out of position as soon as possible, your follow through will be more consistent. This is something that has helped me in my small bore prone. I get the best sight picture, pull the trigger, and let the sights settle back on target and I compare pre shot alignment with post shot. This helps keep down the twitching and pulling that are probably going on as I pull the trigger.
If I'm not shooting, I'm reloading.
