Run before they rush to slap those predictions by calculating the distance, direction, and velocity curve and point out of the ball so that it fits into the rhythm to jump up on the ball and then run.
Run before running Swatter to figure predicted by calculating the distance, direction, speed, curve and the fall of the ball. In order to fit the rhythmic slap jump ball. Then it runs out
Run, before running the slap to think predictions by calculating the distance, direction, velocity, curvature and landing point of the ball. To keep rhythm fit jumping up a ball, then run off.
