Two experiments were conducted to determine the effectiveness of this new memory model. The first experiment examined its advantages in the situation of a free ball, where two opposing players would race to gain control of a ball in the open field. The second experiment examined the accuracy of the model. In both experiments the predictive model was compared against a simple model that was being used previously. The tests were designed to verify that the memory model accurately maintains the positions of stationary objects relative to the client, even when they are out of view.
