*some catchers will stay for a long time in the center of the plate and then make an adjustment as a pitcher starts their motion. Very difficult for a batter to recognize the Catcher's new location after movement.
I like this, but I wonder how much it bothers umpires. My guess is that if a catcher is good/consistent, the umpire will only need a couple pitches to figure out the movement and it won't be a big problem throughout the game.
