You are exactly right tong. With pure push basic there is no fanning. I am thinking variation and preference. If a player has the right elbow "up and out" there will be no fanning. As the right elbow moves "down and at the side" there will be a fanning motion. Still a hit none the less if using the right arm.
With that said, it would only be correct to say you must monitor 3-F-5 and know what Stroke Basic/Elbow Position is needed for your putting stroke.
The preference I threw in the first post probably stems from my desire to have players with their forearms in plane. Meaning I want the wedges in plane with one another so that the putter can move in the same plane as both forearms. This can be done in putting by zeroing out number 3 or placing the club in the life line of the left hand and moving the right elbow closer to "down and at the side."
When swinging a putt the right arm doesn not bend. The putter is moved by the pivot and because the left wrist does not need to cock the right arm will not bend. Here the power is the body.
VJ,
I am interested in learning more on the role of the pivot when swinging.
Thanks
The pivot should be zeroed out. That does not mean you do not move your shoulders because they are a part of the power package. So the most important part of the swinging pivot is plane. You can monitor it two ways. One by making for certain the shoulders are moving on plane. (Find lynn's shooting the plane line drill) Two you can simply trace a straight plane line with the right forearm index finger. I would suggest both, multiple, more, and all. Moving the putter on plane makes hinging so much easier.
