Here's the
Etc. Etc. Etc. part :
Just for a moment subtract Federer off of his weakest grand slam surface (clay), not knocking clay here
just seeing how Federer's greatest rivals perform against him in grand slams minus his weakest surface
And you have this :
Eight losses to Djokovic at all the other GS's
Four losses to Nadal at all the other GS's
Reverse the performance zone and now keep Federer's favourite grand slam surface (grass)
whilst subtracting all the other surfaces to see how Federer's greatest rivals perform against him in grand slams, on Federer's strongest surface
And you have this :
Two losses to Djokovic at his favourite surface slam (the only player to have beaten Federer twice at AELTC)
One loss to Nadal...
Now go to the middle ground and only keep all grand slams played on hard court surfaces
to see how Federer's greatest rivals perform against him, in grand slams, on hard court surfaces
And you have this :
Six losses to Djokovic
Three losses to Nadal
Now compare the big three in finals aggregated against each other :
Nadal leads Federer in finals 14/7
Djokovic leads Federer in finals 11/6 (+ a withdrawal)
Djokovic leads Nadal in finals 14/10
Overall :
Djokovic 25/16 =
+ 9 (+ a withdrawal)
Nadal 24/21 = + 3
Federer 13/25 = - 12
+ 9 Djokovic is symbolic : (if you put Nadal/Federer together you get - 9)
