[O.B.Left]

Push basic with the right forearm parallel to the plane line is great for swift downhill putts because of the automatic vertical hinge it produces. !

Great stuff Okie.

With this procedure do you trace a straight plane line (arc putting, the putter head visually covering the arc of approach, the shaft running along a string line, the putter head riding an inclined plane or putting arc) OR do you use a straight back, straight through (cover the plane line, intentional steering, acceptable when putting although a disruption of the clubs circular orbit, linear force as opposed to the angular we employ on longer shots, pool cue as opposed to baseball bat, the putter running along a straight rail or plane board which is at right angles to ground)? This is my longest sentence to date, over to the hole-ies and pole-ies section.

Although the information you are sharing is almost 50 years old it is nowhere near being common knowledge. There are famous putting instructors out there with popular books or "bibles" even that dont grasp the geometry you refer to, real though it is. Each hinge action having an associated effect on the ball.

I keep re learning the importance of putting with a selected hinge action. To ignore it is to court a mis hit, like a miscue in pool. A disruption of the balls line of compression. The selected motion or arc must stay constant.

Still working my way through 2-C. Let me know where Im wrong.
