So assuming the Harvard U study they're talking about is correct, 34,000 missed strike/ball calls in a season means there are 14 missed pitches/game (34,000/2,430 games). Assuming 125 pitches per team per game, that comes out to an error rate of about 5.5%, which means the home plate umps are correct 94.5% of the time. Acceptable or not? Discuss.
