You must start your swing when the ball is at the distance from the plate, shown in the "Feet traveled during swing" box.


When the decision time is less than 0.175, the pitch becomes extremely difficult to hit.

Your brain and eyes need approximately 0.175 seconds to recognize the speed and direction.
