Ken Murray and Rob Pincus analyze the benefits of videotaping practice sessions at the range. You can learn from your mistakes, since the video doesn’t lie and provides an external perspective for you to dissect your actions from. But making a video of your “perfect practice” runs is very useful also, because experiments have shown that watching perfect form over and over causes mirror neurons in the brain to fire and you can internalize perfect form from this.
