The Swinger using 10-5-E to hit a Draw is not the same thing as the Hitter using 10-5-E as the Angle of Approach Delivery Line. The former Traces the Delivery Line -- 'points at it' with the Clubhead -- whereas the latter 'Covers' it (also with the Clubhead). This Covering -- the Clubhead directly above the Delivery Line -- is 'for real' and not merely visual.

Covering does indeed cause the Hitter's Plane to be steeper. However, it does not cause it to be Vertical. Instead, per 2-J-3, its Angle is dictated by the Clubshaft motions required for the Clubhead to cover the Angle of Approach and its extensions (before Impact Point and after Low Point).

Here is what I am thinking:

All Delivery Lines, including the Angle of Approach, are inscribed on the face of the Inclined Plane. Because the new Plane errected is based on the Angle of Approach (of the old Plane), as we move up the new plane (i.e. go up and in and back), we will pointing at this Delivery Line, but not actually covering it.

Thanks, lets hope I can clear this up!
