It has not been mentioned that using QuesTec does not eliminate human error. Because each player's batting stance is different, the system must be readjusted each time a hitter comes to the plate. This process is done by a human and is one reason lots of people are upset.
The only difference is that, instead of relying on an umpire to call pitches accurately, you are relying on the QuesTec operator to calibrate the machine properly.
