In the book Homer assumes the shaft or more correctly the LCOG (from #3pp to Sweetpot) to travel the inclined plane for plane compliance. But in the audio tapes he discusses a procedure where the Clubhead only travels the Inclined Plane. This latter procedure allows the Clubhead to travel up the Turned Shoulder Plane immediately in Startup . Making for a Clubhead only Inclined Plane of motion with no shift necessary and leaving the Hands beneath the Inclined Plane in Startup. (Not my cup of tea BTW and not what Lynn teaches his students). He also stated that the clubhead only plane of motion was a necessity for complying with the true Angle of Approach Procedure. "Its a clubhead only plane of motion" said Homer. "A Vertical Plane " , "well almost vertical".

But ...... this is probably of little use to anyone except those trying to fully understand the GEOMETRY of the true Angle of Approach PROCEDURE. So far historically , there are probably only a handful of people in that group. Maybe less. Maybe only one, Homer himself. Ted Fort has used the "true" Angle of Approach Procedure in professional tournament play.

BTW it could be argued that everything has an "angle of approach" ... the Right Forearm, the right hip, the right knee , the left testaclese assuming you have one ... Lets not confuse the true Delivery Line of the ClubHEAD Angle of Approach Procedure with any other components "angle of approach", Right Forearm or or or .....Molson Muscle (beer belly).


Short version , if you''re swinging and using a lot of turning and letting things free wheel , unmanipulated so to speak, you are probably planing the LCOG , Sweetspot Plane and thats what we should assume when discussing this the most common of golf procedures. With a Right Forearm angle of approach in mind or a left side Primary Lever Flail action or whatever.

We can restrict the scope to the Impact Interval because Ball response depends on that.

The Lie Angle of the Club affects direction. If the Hands are too low, then the ball goes Left, if too high then the ball goes right. It's named "Swing Plane" because we will Swing the Club along this Plane.

So the Swing Plane is built-in to the club, and it's normally somewhere between the Shoulder and Elbow planes. Our job begins by aligning the ball, low point and the target to this plane. Low point and target are already reconciled. Just get the ball right.

Ben Hogan, in his book "Five Lessons" made an obvious mistake and he himself contradicted this illustration in numerous interviews and demonstrations.
