Default The Ockham rating function

In addition to the new players there is also the issue of inactive
players (vide Kamsky). I have addressed these problems, as well as
inflation/deflation--no such thing in the case of the Ockham rating
lists! In particular, to qualify for the next higher rating list, a
player has to be in the top 1/3 of the players from that higher
list, for say 12 consecutive games, when compared oh her/his current
highest rating list (see the details in one of my earlier postings).


That doesn't stop inflation. The primary cause of inflation is, as I
understand it, new players coming in, giving a bunch of rating points
to the established players and then giving up. Your system does
nothing to stop this, as far as I can see, though the idea of having
stratified lists should slow the propagation of these inflationary
points.
