The process is pure and simple. Remove all non-instinctive movement from your game, which happens seamlessly because the body cooperates fully with any new movement that promotes body safety. There is a swing worth looking for. It is the swing that satisfies the body's quest for balance, rhythm, and spine safety; so it can then focus upon the precision and finesse that will make you great.
Machinelike precision and reliability can only follow instinctive balance, rhythm, and spine safety.
