Are you sure ? I have 6690 for Nadal and 6285 for Federer
for Nadal the difference is the Davis cup final : their points will be taken off later than the WTF final then I include them in the "Race" (as the ATP does) even though they will be taken off by the end of the "calendar year", that is the 31st of december.
For Fed the difference between us must be the 10 points he got for taking part in the first round of Davis cup
... but anyway you can count them off if you want because they probably will not count in the end of the year, Fed counting Basel instead.
There are several ways to count exactly the "Race" (for instance the ATP doesn't count Halle for Nadal) but it's approximately what I said.
