I've been experimenting with the GD system while the pitcher takes warmups between innings. I can see the ball well, but I'm not sure I'd be able to catch a catcher's interference from back there.
And no the plate doesn't move but I do work one field where the plate is pointed at right-center field instead of second base.
If a coach wants to complain that I'm set up too far back, I'll tell them that they're apparently able to see the pitches better than I from the dugout, so I thought I'd try getting farther away too.
