Your only option is then to whip hard and continue to accelerate (or add velocity) till you hit the ball. Once the ball is hit and the signal is received by the brain, thats when you will start decelerating and get into the follow through mode and that would be well past the actual contact point and hence its safe to assume that the peak velocity will be a little after the contact point and not at the contact point or before the contact point.
Sounds very reasonable. Exept for the point that the racket will be slowed down by the contact with the ball, but that really has no importance for the principle in the discussion.
