The day Curt Schilling said he studied tape of the umps so he could figure out their individual strike zone should have been the end of humans behind the plate. Umps have been bringing this on themselves for a long time.
if you have 88 humans doing something which requires judgement, there is no way to have precise consistency. They are calling unbelievable breaking pitches and 100 MOPH fast balls some move laterally, some move down, some are in a straight line.
You will not get machine consistency.
