Would be interested to know what % the 14,441 missed calls is of total pitches. My rough, rough guess is 410,000. So umps missed 3.5% of calls. And 22% of the 14,441 were actually overturned upon review.
Part of me says umps are doing solid job being right 96.5% of time (my guestimate).
But I could also argue for robo ump 100% of time as 78% of missed calls aren't reviewed because not agregious and teams only have 2 reviews.
