You wrote-"These are your opinions and you are entitled to them. But I disagree. I tend to see things differently.

That is why I am here. Why are you here? To what end?"

Arrogance!

You are implying that you are capable of changing your mind, but imply that I am incapable of changing my mind - that I cannot be swayed. Yet the "reality" is that I did change my mind when GBD presented "evidence" of potential camera artifact distortion problems due to focal plane shutters. That's why I changed my mind regarding this "issue" and why I adopted a more equivocal position of ambivalence.

You are free to hold your strong opinion that the clubshaft is really bent forward (while I equivocate about this "issue").

You are also free to ignore, or reinterpret, the fact that the hands are pointing downwards and slightly backwards at impact. You are even free to believe that this appearance is due to camera distortion. However, from my personal perspective, I believe that i) the hands are "really" pointing slightly backwards and ii) that "fact" is biomechnaically incompatible with hitting up-at-the-ball.

I believe that his hands and central clubshaft are facing backwards (and that it is not due to a camera artifact) for two reasons - i) the hands are traveling much slower than the clubhead and therefore they are less susceptible to the problem of camera artifact due to focal plane shutters and because of ii) evidence from other swings.



In this swing, one can clearly see that his hands are ahead of the club as he nears impact, and that the clubshaft is vertical immediately post-impact. That indicates that he is not hitting up-at-the-ball. By the way - the ball is teed behind the white line, which is just ahead of the red colored script.

Also, if the low point is at the point where the clubshaft is vertical, then the low point must be ahead of his left shoulder. The low point is where his left arm is in a straight line with the clubshaft and where it is as straight as he can practically get it - considering the fact that he has a small degree of left elbow bend that causes his straight left forearm/clubshaft to be behind his left elbow but ahead of his left shoulder socket.
