Its not explained very well OB, at least not to me by TGM or people around the TGM because there is no visuals. I saw something done by Chuck Evans last year but it was more just discussion rather than a good graphical explanation.

Ok let me try this again in word form, which is some what handicapped.

Imagine you are sliding your clubshaft along an Inclined Plane board. The shaft points at the Plane Line , Base Line at all times, right? But your eyes do not lie on this Inclined plane. They are way above it. And so, visually , to your eyes the clubhead does not "Cover" the Plane Line. It would if your eyes were on the same plane as your clubshaft. If you scoped the shaft like a rifle say. Instead , visually you see the Clubhead describing an Arc , an arc to a degree consistent with your Plane Angle vis a vis your eyes. The flatter your Plane the more arc your eyes will see. This Arc is inscribed on the ground , it is the Arc of Approach , the arcing clubhead blur you see with your eyes, despite the fact your clubshaft points at all times at the Base of the Plane. I

Its a visual , from your eye line only , a Visual Equivalent to tracing a straight line base line. Its a paralax point of view of the circular club head path , like looking at hula hoop from an off angle as opposed to having your eyes aligned to its plane.

You are making an on plane swing motion but your eye sees the clubhead travel in an arc. To attempt to visually see the clubhead travel a straight line (unless the shaft plane aligns with your eye line or similar) ....logical though it may seem, given our past experiences with pool or billiards etc is to Steer the clubhead, to cover the Plane Line with the Clubhead , visually. Which means that the Shaft is not traveling the Inclined Plane. In fact it leaves it.

All of this is the genesis of the putting Arc gadgit. The arc represents the same geometry as the inclined plane, is the same geometry as the string line that you run your putter shaft along, they all work together............as opposed to the Pelz putting rails say. "Straight back straight through" which, though you would visually see the clubhead cover the plane line would also have shaft leave the string line, on both sides of the ball. Its non planar in a clubshaft sense. The label on your putters shaft describes a "U" shaped arc and leaves the string line. The string line is a horizontal line on the Inclined Plane , which you could imagine as being comprised of hundreds of string lines that when viewed from "down the line" form an inclined plane.

gmbtempe, Its all very confusing in word form , I apologize .... an animation (which hopefully is coming soon) will hopefully allow more people to see the geometry. Once you see it..........you got it.

OB, your explanation reminded me of my college Trig. class

I think if Tiger would read these posts and this forum, he would benefit, greatly. Hell, they all would!

There are different kinds of personalities all with different strengths and weaknesses, HK must have been a "concrete-realist" of some type to be so laser-focused on how our bio-mechanics allow us to stay on plane. Awesome and good for us!

Thanks for the info.
