Agreed. Same reason why Federer underachieved, because Djokodal are much stronger than old Fed, they are tougher competition for Fed, than Fed is to them, because of age difference.Djoker at WI excluding matches vs Federer --> 69-9
Djoker at RG excluding matches vs Nadal --> 71-8
Clayovic is as good as Grassovic but underachieved because Nadal on clay is much stronger than Federer on grass.
Do you agree?
For example AO, what are the stats of big 3, if you exclude their record versus each other? Because Fed has 13 consecutive semi finals at AO, I think, so FEd surely underachieved at AO.
