In his 21 Masters Series tournament wins, Federer had to win 8 three out of five set finals. Whereas, Nadal had to win 5 three out of five set finals. I would weight Federer's tournaments wins as more than Nadal's. Just as I weight Lendl's 5 ATP World Tour Finals (Masters) as more than Federer's 6, because Lendl had to win 5 three out of 5 set finals compared to only 3 for Federer.
