I'm not sure that I like this new rating system.  It gives strength of
schedule too much (IMHO) emphasis. Take this contrived example:
 
2 games played:    Team A - 3     Team A - 1
                   Team B - 9     Team C - 4
 
stats are:
Rank Team    Record   Rec  OpRec  Eff  OpEff  TOTAL
 1   Team C   1-0    1000      0  800   235   2035
 2   Team A   0-2       0   1000  235   775   2010
 3   Team B   1-0    1000      0  750   235   1985
 
So undefeated team B is ranked lower than winless team A.  Perhaps
this anomaly goes away when more games are played.  If every team
played every other team this system might work, but of course they don't.
