It seems that the ATP rules were changed a bit (when ?) regarding a detail about calulations of the rankings. To obtain each player's points, we had to add up :

• 4 Gran Slams
• 8 mandatory M1000 (without Monte-Carlo)
• the ATP Finals
• 6 other best results (MC, ATP500, 250, Davis Cup, OG, etc)

We should now integrate 7 best other performances, instead of 6. That's why all of you won some points this week compared to last standings.

You can of course read some details on the official ATP rulebook, pages 218 to 221. Enjoy !

Please keep us informed if you hear about any other change !
