I think it would be valid to say that how they are positioned at set up is not a good starting point to attempt to determine how much movement.

I think creating a marker at impact and then applying it backwards might be more valid.

With the exception of Mac, the movement between frame 1 and frame 2 appears to be more than the movement between frame 2 and frame 6.

Wonder if asked of each, what would they look like if they were asked to set up to the ball as if you at impact? Guess I am wondering if they know where they are going, or they know what they want out of feel and it results in them getting there?
