What does this all mean? It means that there is no one perfect swing method. The method chosen for this instruction manual is a collection of those bits and pieces of swing theories that both work together as a unit, and probably most importantly, are most easily learned and repeatable for consistency.
Consider that a well-groomed golf swing is much like a choreographed dance step. All of the movements are already pre-planned and laid-out. All you must do is fully understand and memorize them, and execute them enough times so that your body can easily respond to your mental instructions.
Also included with the swing instructions are analytical instructions to help to you to be your own 'swing doctor' in order to fine tune your body motions.
