^^^ I have long believed that the pocketing in the dwell time holds answers to many mysteries. One of them that I understood was how the racket seemed to be moving up at contact on many first serves, but the ball came out a degree or so below horizontal. The answer I found is that the racket tip completes its apex turn during the dwell time in those serves, and actually launches the ball sightly down at the end of it.
