All pros walk up, and along the shot line the same way EVERY time, unless they are in a very unnatural shooting position. Like the front AZ page with Dodong shooting up/over..... this same mindset still applies and they will also work on that walk up by watching the results/outcome of their ''body actions''/results and mistakes or makes or misses'....the results are their teachers.
By doing this your being ''consistent'' in your body actions/movements before your ''down and done''.
When your ''down and done''....and, your missing a shot the same way every time by hitting it too thick or too thin that's good, that's correctable.
If your all over the place, then your fundamentals MUST be fixed FIRST.
