But I'm worried that the umps would start to second guess themselves or just lean on the technology too much. They'd start to make a strike call, hear the beep and then the re-thinking and hesitation comes in. I don't think it'll matter how quickly the beep comes. Balls & strike determination is almost immediate as it is now. There might be a slight delay in making the signal, but the determination is almost instinctual and automatic. I certainly don't want umps out there who are continually questioning their own eyes.
