Clubhead Delivery Lines -- Angle of Approach Versus 'True Geometric'

Bucket is on the money here, but this is sticky stuff, and I want to give those readers interested ample opportunity to understand it.
Remember, the Plane Line is the 5th Component of the selected Stroke Pattern. It is that Line defined by the intersection of the Angled Plane of the Stroke and the horizontal plane of the ground, and it can be aligned on the Target Line (Square) or to its left (Open) or right (Closed).
In contrast, the Plane Angle and any Variation are Components #6 and #7. Here we are talking about the original Angle of Inclination of the Plane and any Shifts that may occur in this Angle during the Stroke. Any Shift in Plane Angle has no effect on the selected Plane Line (1-L-#18 ).
The important point here is that the Hitter's Angle of Approach procedure uses the Closed Plane Line of 10-5-E as the Guideline to the Stroke, but it does NOT use that Line as a new 'true Geometric Plane Line' (2-J-3). Such a Baseline would not only be aligned to the right of Target, it would also come complete with its own unique set of Arc and Angle of Approaches. These would conflict with the Arc and Angle of Approach of the original Geometric Plane Line, and the result would be an Inside-Out Stroke, not just an Inside-Out Impact (2-J-2; 2-N-0).
So, just how does the Hitter use the 10-5-E Delivery Line? He uses it as a Track that he covers with the Clubhead throughout the Stroke. Personally, I visualize a bowling alley gutter moving up the Angle of Attack, with the bowling ball (clubhead) remaining in the gutter during the Stroke (and not moving inside or outside it at any time). This is the Wheel TRACK Delivery Path of 7-23. And the necessarily steep Plane Angle erected on this Delivery Line must agree with the requirement to cover -- not merely 'point at' -- the Angle of Approach Delivery Line.
Summarizing, the Angle of Approach procedure uses the 10-5-E Plane Line as a Clubhead Delivery Line, but NOT as a true Geometric Plane Line. Otherwise, there would be an Angle of Approach to that new Baseline. And as Bucket has stated, the new Plane Line IS the Angle of Approach (of the original Geometric Plane Line).
