The more I shoot the more I NEED to focus on the fundamentals. Without constant physical focus the fundamentals just deteriorate with each round downrange - the whole practice makes permanent but only perfect practice makes perfect deal.
With drawing, the faster I try going the worse my fundamentals get, resulting in superflous motion and slower times. Focusing on going fast - or without even trying, if I'm just amped up on adrenalin going into a stage - my hand movement backward to access overshoots the position of the tang on the pistol resulting in my coming out of the holster with a low grip. Rather than focusing on speed I focus instead on what I term, "short drawing", concentrating on the feel of the pistol against the side of my body while awaiting the buzzer and limiting my hand movement to the shortest travel necessary to access the grip. Changing my visualization from speed to shortening my movement promotes economy of motion producing a more consistent grip, faster raw times, and better hits on target.
Take this with a grain of salt however Lugnut as I'm no better a shooter than you (in fact, far worse with a revo), and struggle with the same challenges.
