I have watched, and practiced, EVERYTHING Tor has produced. I have a Master's on the BU exam (7ft.Table, so couldn't get a phd) I recently had a lesson with Scott Lee that has done more good then all the rest.
Not necessarily because of any groundbreaking insights, but because he was able to break down my psr, my eye pattern, and my stroke frame by frame and millisecond by millisecond. This showed me what my head, shoulder, and wrist were doing on various shot speeds, and why I was not consistent throughout the course of a match.
I dont know what Scott's FR is, but I do know his instruction has helped me shoot straighter with more consistency than a couple of years of watching tor's YouTube videos ever did.
There is something to be said for having a coach there with you pointing out corrections in your stroke. JMO.
