I wanted to read your paper after I watched the video.
The video is very average because it does not provide sufficient detail on how to perform several of the actions he is recommending. I found a video such as SnT much better because they are providing actual baselines where you should be and not generalizations.
However I am surprised that you did not mention the most interesting part of the video, IMO, which was his discussion about low point. He stated that the head should be in front of the ball and more or less line up with the clubs low point in an iron swing. This would place it anywhere from 2"-6" in front of the ball. I believe he stated as well that the head should be moving forward in the downswing.
Now Mac wants the head to move forward as well but the difference is it looks like SF places the ball in the center of his stance were Mac wants it in the Hogan position so you move forward but do not get in front of the ball.
