I think (but the programers on high can correct me) that there are a
few non-pawn stars but over 10 games only because they had so
many games going before the 10 game rule was enforced. You used
to be able to accept open invites or be challenged above your allotted
10, but not now (there was 1 guy who was 3rd on the MAP tables, but
had no star!)
Their number of games should be decreasing gradually until it is
below 10 again. If not, there's a loophole that probably should be
closed.
