TW, Mooresville, 5/10, plan to be there.
Rob is giving great advice on the reality of shooting for defense. But I'm not sure your getting your answer, Rob broadened the response quite a bit, and is exactly right in application, shoot until the threat is down ( Golden ), but how do you practice, and how do you evaluate, how you are doing, when applying the multiple shot on target concept, not to mention, getting out of the way at the same time, ( getting off the X ) ? Practice, and make sure you are getting a great grip, not a good grip when firing, and listen to fast shots, get a cadence in your mind, some may disagree, but for practice, you need a goal ingrained in your mind, to get faster, you need a motivation, other than your need, a Cheetah chasing you is a lot of motivation, a bad guy is too. That experience will motivate you to the next level, that I think you want to come to ( in practice ). Practice is key, but with a goal, and good motivation. Dry fire, and live fire, but get it in your mind about how fast. A firm stance, grip, and application, will let you shoot fast and accurate, especially within 10 yrds... If you can watch the CFS stuff, by all means watch them.
Remember, once a level of experience and ability has been achieved, it sticks around, for a long time, even if you don't practice for a while, the body remembers what it used to do. You might not be able to win matches, but you will still be above average.
I know Rob will have a response to this and is welcome.
