Am I over thinking when I don't think it's possible for an umpire to separate his eyeballs and look at the instance a runner releases from first base on a steal attempt and the other eyeball looking at the exact moment a pitcher releases the pitch from her hand. In a high school game the runner was called out for leaving early. Video screenshot clearly showed she did not leave early. Is it just a guessing situation. I understand the very obvious ones where it's clear to everyone in the park but the close ones seem to be a guessing game.
