1. With the On Line procedure (Arc of Approach), you Trace the true Geometric Plane Line (Basic Delivery Line) with the Sweetspot. With the Cross Line procedure, (Angle of Approach), you Cover the Angle of Approach with the Sweetspot. With both procedures, you Trace the selected Line with the Right Forearm and #3 Pressure Point.

2.Yes, 1-L #6 (the On Plane Clubshaft) refers to the Geometric Plane Line. And yes, when using the Angle of Approach procedure, the linear nature of the Hitter's Right Triceps Thrust through Impact drives the Club above this Geometric Plane Line, i.e., into 'right field'. This 'off Geometric Plane' Drive-Out does, in fact, violate the true On Plane Clubshaft requirement of 1-L #6.

However, as long as (1) the Clubhead passes through the same two points (Impact Point and Low Point) located respectively on the Geometric and Low Point Plane Lines and (2) both the Clubshaft and Lag Pressure Point (as directed and supported by the Right Forearm) are correctly aligned (as established at Impact Fix) to this alternate Delivery Line (the Angle of Approach), then the geometrical equivalent of the On Plane Clubshaft has been achieved (2-N-0). And that is all that is required.

Relevant portion of 2-N-0:

The “Delivery Line” procedure completely replaces the geometric Plane Line (2-F) and the Target Line because these were established at Impact Fix (7-8 ) according to the intended Hinge Action (2-J-1) and Stance Line (10-5) requirements, and their control is completely automatic. Both the Lag Pressure Point and the Clubshaft must so relate to the selected Plane Line OR Angle of Approach – to the geometric or the visual – but don’t try to Monitor both at the same time because, though equally dependable, they need not be identical in execution AS LONG AS THE CLUBSHAFT HOLDS A STRAIGHT LINE RELATIONSHIP TO A STRAIGHT LINE – POINTING AT A STRAIGHT LINE.

For visual reference turn the book UPSIDE DOWN and look at pictures 2-C-1 #2B and 2-C-1 #2B. 2-C-1 #2B upside down is the "optical illusion - ON THE GROUND." All that is omitted from 2-C-1 #2B is the Impact Plane Line and the Low Point Plane Line.
