So there is a “Clubshaft” Plane and a “Sweet Spot,” or “Swing”, Plane. But herein, unless otherwise noted, “Plane Angle” and “Plane Line” always refer to the Center of Gravity application.
SWEET SPOT
Example – a plumb bob.
Mechanical – The longitudinal Center of Gravity of a length of material.
Golf – The spot on the Clubface through which a plumb-bob line would pass if suspended from the Grip area.
I stress again: "...unless otherwise noted..."
An example of this would be in 2-C-1 #1 where the Inclined Plane is not the Sweet Spot Plane.
But otherwise, the Inclined Plane is the Sweet Spot Plane. And Plane Line is the Sweet Spot Plane Line.
Interesting Homer chose to use the phrasing at least 4 times, the use of 'herein'.
'Herein' does it reflect upon the entire document or that paragraph/section?
1-H at least three instances of herein.
2-F (Plane Angle and Plane Line refers to Center of Gravity application)
2-N-0 (Plane Line means Impact Plane Line) Granted it is on the Sweet Spot Plane, but it is not the base of the Sweet Spot Plane. So from page 2-N-0 (p39) the base of the Sweet Spot Plane in no longer the Plane Line but it is now the Impact Plane Line which is physically above the ground for the rest of the book unless otherwise noted?!
6-C-2-0 refereence Herein which IMO has made everyone believe the PP#3 is the lag pressure point. But that was for convience and Homer's choice of grips IMO. By the way Yoda and I disagree on this point Big Time. But I submit to you grip 10-2-F, PP#3 is now on the bottom of the shaft... But this 'herein' doesn't create confusion as does the ones in 2-F and 2-N-0.
I provided sufficent references that if you can resolve how the Golf Club Shaft can lay flat on the Inclined Plane whose base line is the Plane Line and the Angle of the Inclined Plane is the Sweet Spot Plane and Angle definition then you have done something no one else has been able to do. Put simply, you can not have the club shaft flat on an Inclined Plane as defined by the Sweet Spot Plane and Angle that would be identified at Impact Fix. Can't be done... 1-L is the mechanics, the golden rule as I understand it. It would be a hosle rocket or a bent plane to get the ball on the clubface.
If you go through all those references, do it your way always defining it as the Sweet Spot Plane/Angle/line and verify it to the other relationships (lines) Especailly 10-5, text and drawings and 1-L-5/6/16/17/19 and 2-C-1#1 is pretty clear as well.
Homer's Sweet Spot Plane Concept as I state before is the 'Feel', you don't want to be thinking ture geomteric Clubshaft Plane or Inclined Plane when what you want to hit the ball with is an 1 inch or so to the outside of that line. My issue he should have specified which was which as he used the word. This is a case of brevity has led to confusion, misunderstanding, etc. As clearly witnessed by responses or lack of response IMO.
I just started a new thread in The Lab, "the illusive and invisible sweetspot plane". It's in there because it might be a little over the top for those that live by the K.I.S.S. mantra.
