The real plateau
The issue that holds most shooters back has less to do with talent and more to do with what they reward during practice.
A shooter can break a target with bad movement and miss one with good movement. If score is the only feedback, practice quietly reinforces the wrong things.
Open-loop learning
Shooting is not a closed-loop skill. Once the movement begins, the conscious mind cannot keep editing it in real time.
That is why training has to value movement quality, visual clarity, and setup discipline before it values whether one target broke.
The practical shift
The shooter has to be willing to get temporarily worse while building a better movement pattern.
That is not a motivational idea. It is a requirement of learning a skill where the result often arrives too late to explain the movement.
