Club heads must maintain a steady center to allow for control of both the path and depth. A perfectly controlled arch determines which direction the club heads travel and where the ball hits the club’s face.
To complete the circle, the pin must be in its original place. We will have more consistent and accurate club ball contact if we are able to maintain an in-space swing circle center. This will also allow us to achieve greater club head speed.
Twirling a length of string with a weight attached to it will show why you have more club head speed. You can try this: swing a weight (or a keyring) and move your hand around a circle. Slowly, make the center rotation as small as possible. The weight will move slowly if the center of your arc is moving as you swing it. If the arc becomes smaller, the weight literally zooms around.
Unbalanced wheels cannot spin as fast as balanced ones. The golf swing must have a steady center in order to create speed as well as the precision contact that we want.
The most critical task when we are addressing the ball is to pinpoint the location of its swing circle center. This is done by measuring the club with the other tool, the left-angled right arm. It is crucial to accurately measure the club and maintain it for a successful shot.
The swing circle center can move around, causing us to lose speed as well as the ability to return exactly to where we measured.
