Geometry of the Circle
Quote:
2-N-0 CLUBHEAD LINE OF FLIGHT The line of flight of the Clubhead and the Line of Flight of the ball are not the same but touch momentarily during Impact. The one has a vertical plane of action, the other an Inclined Plane. This involves the Angles of Approach (2-J-3) established by the Left-Shoulder-to-Ball relationship of the Lever Assemblies 1-L-11. This line cuts diagonally across the face of the Inclined Plane and passes through both the Impact Point and the Low Point. These points also locate parallel Plane Lines passing through them – that is, the Impact Plane Line and the Low Point Plane Line, each of which must use the “Sweet Spot” Plane (2-F). Herein, “Plane Line” means the Impact Plane Line and “Low Point” means Low Point Plane Line.
Below are Full-Scale illustrations of the "Geometry of the Circle". Driver with the Ball played 3 inches aft of Low-Point; Wedge with the Ball played 3 inches aft of Low-Point; and a Wedge with the Ball played 6 inches aft of Low-Point.

Of interest is that when the Ball is played 6 inches aft of Low-Point (about the Left ear) with a wedge, the divot would be almost excessive. Use a Tee.

For O.B. Left.....

If Separation Occurs at Low-Point, then, without a Tee, the Club would strike the ground before Impact.
