With the robo-umps thing, at current technology would that be fast enough? It seems like with the challenges, the challenger has two seconds to challenge, the ump announces, and it takes another second or two to display the result. So it's actually taking 3-4 seconds or more to get to the correct call. That much time isn't required for the actual technology to make the call? If the system knew that EVERY call was getting read, the technology could be set so that the call could be made in 1 second, yes? The delay from pitch-to-call, or from tap-to-call wouldn't need to be as slow as is reality now, I assume?
*IF* it actually takes 3-4 seconds for the technology to make the correct call, that might be a reason not to go full-robo.
