The original poster said "Djokovic is starting to beat Federer every occasion they play" - that is what I was replying to.
I didn't give the wins/losses any weighting or importance, just the fact the OP was wrong unless you only consider results since the 1st Jan which is a bit self-serving in terms of trying to portray a trend imo. Using the same logic you can show Nadal is barely a top 10 player (having lost to both Davydenko and Ferrer in the same date range) - which we know is not the case.
OK, he should have said: he beats Fed in the most important matches, at least on outdoor hard. No matter how defensive you are about it, it's never happened before that Fed would get beaten in 2 hard court slams in a row, even less by the same player. It may not be that terrible of a sign, but it can't be good either.
Don't bring Nadal into this because hard court has never been Nadal's best surface and Nadal has never dominated the hard court slams the way Fed has. There is nothing unusual about Rafa not winning on hard.
Fed losing 2 hard court slams in a row to Djoko is about the equivalent of Rafa losing 2 RG or 2 masters in a row on clay to the same player.
If that happened, I'm pretty sure you and other Fed fans would not dismiss it as meaning nothing special...
