One more point, Stephen:
Points _per game_
is clearly a stat that lends itself to moderator
bias (as anyone who has ever had Ahmed read for them
will readily admit :).
Points _per tossup_,
however, corrects for most, if not all of that bias, and
is a much fairer way of making comparisons, if such
comparisons need to be made. [Likewise, simply using points
as a criterion for Swiss pair matchups is not in and
of itself fair, but using points per TU would
be.]
