The reality is that if Nadal had made it to more hard court slams earlier, there may have been a difference, particularly before 2008. But, we will never know. It would have likely been very different if Federer weren't the greatest clay court player in the world for about six years outside of Nadal. If he had fallen short of all of those finals in Paris, the record would be closer or he may have dominated Nadal more on hard courts even back then. It is all conjecture, as it could have gone the other way even though I doubt it. Roger would not be one to want his major record to NOT include all those finals losses to Nadal in Paris--they demonstrate he was a complete player and won across all surfaces and went to a record number of consecutive major finals not once, but twice! These are all compelling stats for him. Rafael Nadal on clay is other-worldly and he just proved it again. He could win three or more of these at this rate. It is a beautiful thing, for Federer was so superior to everyone for so long he may have had two calendar year slams and 23 majors or whatever if Nadal had not come along. Superman met his kryptonite.
