pete did the serve right.
too much wasting of time only leads to a loss of rhythm in my own estimation.
I know all these players have their rituals and I had them too but too much time on the service line leads to some loss of serving rhythm in my book.
Nole does it when he needs to concentrate and needs a few more seconds. Not sure his success ratio on those serves. I can't imagine being all that effective, really since the idea for him is to play the ball and get engaged in the rally. Pete serves to win the point.
