Thanks for the encouragement John, I'm glad someone understands the frame by frame advance experiment. It's a real eye opener if you bother to try it.
A slow camera shutter speed will also give a "blurred" racket when it reaches it's highest velocity.
I noticed this years ago by accident after reviewing tapes I made from U.S. Open matches with a slower shutter setting. The blurring effect doesn't occur until much later in the swing, even in players with high take-backs.
It made me reconsider the contribution of a large backswing and helped me discover a much more important contributor to racket acceleration.
I'm sure that the technology Brian has access to can get some instantaneous velocities that would confirm the click thru experiment finding, in a more quantitative way. I look forward to seeing those numbers.
