100% may not be possible I guess, but if you check the calibration for the system before each game, it should be darn close to it. And even if it isn't, at least the system will be 100% within whatever zone it is calling, unlike umpires who have different zones for right handers, left handers, rookies, catchers, veterans, guys they have had run ins with, catchers who disagreed with a call, a pitcher who looked back at him wrong over a call.....
