Following is a diagram to help explain Ball Location and it's affect on Plane Angle. Basically, the farther back from Low-Point the Ball is Located, then the Steeper the Plane Angle.

Homer Kelley's method is geometrically correct and allows Low-Point to remain at the Left Shoulder. In addition, it automatically adjusts the Angle of Approach.







Notice that the original Plane Line, inscribed on the surface of the Inclined Plane is still present. Step 4. It's below ground.

Geometry of the Circle:
The implications of these "Alignments" are significant. As the Plane Angle Steepens for any given Club Length, the Club length decreases, which requires increased Hookface (Adjustment), which increases the Clubface Closing Ratio, which corresponds to the wider Angle of Approach of the aft Ball Location.

This means that for any ONE Plane Angle for any given Club, there is only ONE Ball Location that Hinge Action can produce Straight-away Flight without disturbing Low-Point Location.

Plane Angle, Ball Location, Hookface (closing Ratio) are inextricably related. Change one and you must change the other two to produce Straight-Away Ball Flight.
