Every repetition is the diagnostic rep. Without any feedback on a repetition, it’s just a repetition. Making gains in motor-mechanics requires some feedback loop so we get a sense of our performance and make improvements thereupon.
If you see a dash, strive to make it a dot. If you are off target, then put more awareness in your grip in your next repetition so you have an appreciation for the feel of the gun to align the muzzle. If it’s a far target and you miss, then again, focus on your grip and your natural point of aim as well as a bit more front sight awareness.
Strive for the relentless pursuit of ultimate speed and accuracy by diagnosing every repetition. It doesn’t take any extra time; it only takes a little bit of feedback and awareness.
