Your question is why do I represent the end-backswing position with a single photographic image, and you seem to imply that it might not demonstrate the "true" amount of left-lateral pelvic/weight shift seen in the final moments of the backswing.

First of all, I produce only a single end-backswing image for simplicity sake. Secondly, let me define what represents my definition of the end-backswing - it is the time-point when the clubshaft starts to move in the opposite direction. So, using a swing analyser program, I advance the video frame-by-frame until the clubhead starts to change direction. I then back off one-frame, and that represents the end-backswing position - and it incorporates Hogan's final left-lateral pelvic shift in the final moments of the backswing. As your series of images demonstrates, if I was off by a single frame, it would have very little effect one one's overall impression.

I did the same process with another swing video of Hogan. I waited until the clubshaft changed directions to determine the end-backswing position.



The blue-colored area represents that part of Hogan's body that 'appears" to be right of the center of his stance at the end-backswing position.

Anticipating that you may claim that my single-frame representation of the end-backswing doesn't accurately represent the end-backswing position, I have produced the following series of images.



I advanced the video one frame at a time. Image 4 shows the clubhead changing direction. Therefore. image 3 accurately represents the end-backswing position (and includes the left-lateral pelvic slide that occurs in the final moments of his backswing). Look at his clubhead position in image 3, and note that it is in the same position as my single-image representation of the end-backswing in the previous series of images. I do not believe that there is any foundation for any "belief" that I am deliberately misrepresenting reality.
