But I guess it would be possible to keep a rough note of points accumulated throughout the season.
I have suggested to do that as Judio already makes the rankings, but I will not start before the Australian Open since it's useless in the very beginning of the year.
Anyway, after Paris tournaments, the rankings and the Race were the same except for players who had played challengers (or lost in qualifyings).
Then they can use the rankings to determine the participants to the "ATP World Tour Final" (ie Masters Cup) :
the rules to determine these participants which Judio displayed are exactly the same as last year.
