I bet it is standardized...to european standards. That's one of the beefs with the MM E16 like I have. But the slot is too shallow (about 3/16") for an aftermarket miter guage. Didn't bother me that much, as I don't see using a miter guage on the BS anyway. And if I find a need to, I have the factory one to use.
But, it could be the top was just cut wrong and no one caught it. Hopefully Ken and some of the others with the MM16 will shout back witht their findings. Jim.
