If you experience an umpire consistently calling pitches 6+ inches off the plate a strike .....then what you have is not an Umpire......he is a cheat....
I dont work with cheaters....
If I had a partner who was doing that, we would get to the middle of the first inning and we would have a "Come to Jesus" meeting.....or he would be doing the rest of the game alone....
If you experience this regularly, then the umpire is either beyond awful, cheating or sticking it in your teams ear....
Questec is a MLB tool. although I would welcome the opportunity to train with it, I doubt I will ever see it in college or HS umpiring.
