Correct me if I'm wrong, but center-cut and center shot are two different things, right?
Center shot, means that the arrow shelf is cut past center, allowing the center of the arrow to be the mid-point, not the shelf as is the case in center-cut.
Which also means that the arrows spine-thickness must be double of the negative shelf cut dimension to get centered correctly. (or less if a strike plate is installed)..
Jim Neaves of Centaur will cut the arrow-shelves past center if Dymondwood or Micarta is the main riser material..
