The slaughter blitz 9x9 tournament pushed up my rating and now my ratings are:
Blitz: 702 Live: 652 Correspondence: 680
Overall: 713
Mind you, I am not complaining :-), but the overall rank seems kind of strange. Or do the categories not inlude 9x9 games?
The overall rating is not the mean of the partitial ratings! your overall rating was higher than your blitz rating, so winning lots of blitz games pushed both your overall and your blitz rating with an offset between them.
