Well he's 1-1 vs Nadal this year (had to beat him to win Indian Wells) and 2-1 vs Djokovic (1-1 in slams) so its not like he did a Davydenko and got all his points in the post US Open window.
Although I see what you mean - Djokovic and Nadal have been in better overall form whereas Federer has been a lot more vulnerable. But I guess if you keep putting yourself in these type of positions something will go your way eventually.
This could very well be redundant come Sunday. Murray's new attitude could be the difference. At least if he wins then it will be good for men's tennis in general.
Then Delpo and Soderling hit top form again. Suddenly we have a solid top 10.
