At risk of looking "nit-picky"....plane line OR DELIVERY LINE ...if you are using one of the alternate Delivery Line procedures...of course those being derived from the original Plane Line...
Agreed, along the Arc or Angle of Approach .... visually from the players perspective . Along the path of the club head blur so to speak . Or, along the club head path as seen in 3d space..... meaning the Aiming Point is not on the plane line except for balls played at low point.
Once again, from pg 83, in the context of compensation for different length clubs:
--2. move the Ball forward or aft of the established Aiming Point...
which would make no sense were the Aiming Point not on the Plane Line. The ball is never moved fore or aft on a delivery line.
Hey MJ.
By "Plane Line" I was referring to Low Point Plane Line , the Base of the Plane . As distinct form the IMpact Plane Line. The ball played at low point will sit on the Base Line Plane Line aka the Low Point Plane Line and the Impact Plane Line . But as the ball is moved back in the stance ... BACK , UP the plane and IN (3 dimensional ) along the on plane , circular club head orbit aka the delivery line of the club head, the distance between the Impact Plane Line and the Low Point Plane Line increase, widen . The ball played back in the stance sits on the Impact Plane Line but not the Low Point Plane Line or "plane line" in common speak.
Ah geometry in words, it sucks ...
You have to move the ball back along the delivery line of the club head assuming you want the club head to meet up with the ball.
Heres a diagram. Disregard the arrow , that curve from impact to low point along the circular club head orbit is the Delivery Line (and the Arc of Attack).
The ball is always moved fore or aft on the Plane Line when adjusting for different clubs.
Could be on the delivery line to...all delivery lines include the ball and the aiming point if need be....so you can be aft/forward on the delivery line as well.
