Yes, agreed, perhaps I'm not stating the question properly - given that it is
on plane - and that we are driving DOWN plane - is it a 'directly down' (90
degrees - down in front of right foot) vs 'directly forward' (straight at the
target) vs. somewhere in between - halfway being a 45 degree angle with the
ground.

If you were going to put a shaft in the ground on the angle of the endless
belt, from top hand position to aiming point, and that shaft was your
angle/arc of approach what angle what the shaft make with the ground given a
fixed impact hand location, ball position adjusted for club length, and
constant angle between the upper left arm and shoulder line/axis tilt at
impact.


What is the ON PLANE angle of approach that the hands make in such a case?

Your question seems to refer to the Angle of Attack (the Downward
Dimension of the Three Dimensional Impact per 2-C-0 and 2-C-1 #2B). However,
the term you have used is the Angle of Approach (the Forward
Dimension per 2-C-0 and 2-C-1 #3). Please confirm you mean Attack Angle or
else reiterate Approach Angle.
