Tell me how he lied when the person hitting was a volunteer from the crowd and the trajectories were computed automatically and no one was near the simulators computer and when the player topped the ball the trajectory plot showed just that, the ball rolling on the ground. The data was projected where every one could see it. He demonstrated it with two different guys of different abilities with the same results. No chance for cheating on these results.
