This is just not correct.  There is a certain amount of variability in
how human beings hit a tennis ball.  That's why human beings don't hit
an ace every time.  Since you say that the players are limited to the
physiological constraints of the human body, that means that my
simulated player would neither know the exact position of the ball nor
be able to hit the ball in exactly the way that I would like.  Sure I
know the formulas.  So do real players on real tennis courts, for that
matter.  But neither of us can hit the ball however we would like to,
just because we have the knowledge of what would happen if we could.
