I had to change my mind because I was proven wrong. I originally took the position that Moe Norman shifted planes during the backswing - based on an analysis of this swing video.

This is a photo series form that swing video.



It looks like Moe Norman is on shallower, but parallel, plane in mid-backswing. However, I now realize that my interpretation of a plane shift was wrong and that it was due to camera angle distortion-error. I only realized that Moe Norman really stayed on the same plane when I had the opportunity to analyse a swing video from an up-the-line (rather than down-the-line) swing video where there was far less camera angle parallax error problems. I then realized that Moe Norman really had a zero-plane shift swing.

As a Popperian, I was forced to change my opinion when my original opinion was falsified by "solid" contrary evidence. Later in that forum's thread, I admitted I was wrong and I produced this photo-series showing how Moe Norman's clubshaft stayed on the same plane during the backswing and downswing.
