doesn't consider the 3D space, but rather the box half way through the plate, which is not consistent with the rules:

"Currently, the ABS makes calls based on where the ball crosses at the midpoint of home plate, 8 1/2 inches from the front and back of the base."

Don't confuse this with the box you see on your TV screen. ABS can be extremely accurate. It's just interesting that they aren't using the full 3D strike zone for it, and it's also interesting that they don't want to use the actual rules to define it:

"One of the "technical issues" that MLB and the Players Association are trying to work out is the shape of the automated strike zone. Apparently, neither side wants the zone to be called as the rulebook states, which is the shape of a cube measuring roughly from the batter's armpits to his knees."
