1. I like Kelvin M's work because it puts a lot into the incubator. BUT this months article is more confusion an I don't Understand the points yet.
2.As KM stated "Dr. Sheldon Cooper of the Big Bang Theory" may have said but he is good only for entertainment. I am familiar with Dr. Arno Penzias, also of the Big Bang Theory but I do not think he does golf.
3. O.B.Left video of the shifting plane is very usefull. If I may add a comment- the plane is not shifted during the LOWER 180 Deg. of the clubshaft arc, ie. the plane dose not shift after the elbow plane ( or whatever U choose) is established. This is important.
4. pictures for plane analysis must be taken with care. the pix in the article are not good. If the pix is accurate and looking at the edge of a flat plane then the plane angle line will lie EXACTLY on the base line.

Just a general note on # 3.
That video shows just one of a myriad of possible plane angle shifts or none at all for that matter.
If you traced the clubhead (sweetspot) with dots you'd see a 2 D flat to plane circle for the (theoretical) zero shift procedure but then as you plane shift more ...beautiful curves would appear as you approach Furykian near constant shifting . (3 dimensional clubhead orbits ). Picasso like curves in their perfection.
Who was the mid century golfer who described a plane shift in the downswing as "paint my Picasso" ? Cant remember. Henry Cotton? Elk talked about it. Thinking he was British for some reason.
My apologies if i sound like a planeologist. I prefer the term Circleist. Cant understand ovals without first understanding circles. Cant undertand the effects on the clubhead orbit of shifting until you understand zero shift.
Not saying Kelvin was wrong, I hate those "shaft lines" too. But guys , professionals who know their golf geometry should not be discredited by the mistakes, false assumptions of others . A lot of which we're created back in the early days of video analysis . It was like "hey we got this video machine now ... .what the heck are we gonna draw on the screen?" Took a while to figure it all out. A long while.
Interestingly , position golf seems to have come into vogue around the time that photographs were included in golf books. It was sorta like ... " Ok here I am at the top of my backswing , club parallel to the ground".
Are we seeing a trend here? Are there false assumptions being drawn from todays doppler radar? I dunno. Maybe by some.
