Also, no one mentioned this...your score is your points per second, called your hit factor. That's what you are chasing. Work on shooting mostly Alphas, but don't worry about some charlies in there. Deltas can really add up fast and misses are obviously bad, so avoid those, but this is not a bullseye match. As you gain experience you'll be able to determine when you can get good hits on a target with a somewhat blurry sight picture and when you have to have a solid fundamentals (sight picture, trigger press) to make the shots that matter.
