I'm not sure how if there is a way to do something correct more often than the current way, that we shouldn't accept that way. To me, this is like saying "when I go to a fast food restaurant, they get my order correct 90% of the time (that's being generous, honestly), but that's the way it's always been done, so I'm ok with that". No! If there's a way for them to do it better, I want them to implement those ways. If using an electronic system, either in whole or part makes the strikezone more consistent, then I don't care about the tradition or "nuance". These dudes play their butts off for 7 or 8 months out of the year, and to say that we're ok with umpire human error being the deciding factor in even a handful of games is silly, if there are ways to remove that.
