Perhaps there is an overlap? So starter can be 2 balls or 3 balls. And allstar can be 3 balls or 4 balls. And MVP can be 4 balls or 5 balls.
Just a thought.
I have seen no evidence of this, in fact I have seen more the other way. I was just throwing it out there.
To me, the possibility of different rounding is perhaps the most likely explanation. Either that, or the classes are fixed and maybe just a bit more work needs to be done to tweak the FAQ.
