This year the WTF starts on the 5th of november, hence one week before the date when you say the points from the WTF last year drop out.
Basel and Bercy are one week earlier this year, and the WTF is 2 weeks earlier.
Besides, the points from all ATP tour (and challenger I think) tournaments from last year and from the WTF always drop out after the final ATP tour tournament from this year, which means after Bercy this year.
Actually, I've gone back to the rulebook (at least the version I had the beginning of the year : if there's been an update since, thanks for telling me as, once again, I don't have access to the ATP website at my work), and it says :
- that the points from the WTF drop "on the monday following the last ATP world Tour event of the following year" ... that is the 5th of november
- but it says that all of the other events stay for 52 weeks, which means that ... the points from Bercy last year should drop one week after the points from the WTF
!! Hence the 12th of november. Which is clearly crazy
One evidence imo that it will not happen like that is that the "year-to-date rankings" or "road-to-London-rankings" (that is the former "Race") released by the ATP do not take into account Bercy from last year.
That's why I guess that the points from Bercy last year and even the points from all challengers from 2011 will drop after Bercy this year, that is the 5th of november.
But this is clearly a topic we should discuss in the "ATP rankings thread", not here.
Except if anyone has a clear answer, this topic doesn't need to be discussed over and over in this thread, I will write something about that in the "rankings" thread to start the talking.
