If I did not know any better...

So if your zone is still 17", but you're not calling pitches on the inside corner when F2 sets up outside, I assume this means your zone extends outside past the glove a bit.

Now, same catcher sets up inside, so you give him a couple of extra inches inside while taking away a bit outside.

How the heck are batters to know what you're going to call a strike? So, now, they need to get into the box and watch the catcher to figure out where the zone's going to be for that pitch? Do we not see the problem here - essentially the batter now has to protect 25-30 inches across. Don't you think that's a bit much?
