I was calculating some, not sure, but if Fed wins here he adds 400 pts, and with Novaks bad luck in London and Fed win Nole might lose No.1 to Fed. Hypothetical.
What i dont like at these injuries, or "injuries", it might take some value of it. I remember when Djoker was winning some 41 continuous matches, then there was walkover over Fed i think, and also one player was injured, so he just skipped to be with most continuous wins. Then he lost by Fed in RG.
In Nadal case, i would get rest, skip London. That terrain isn't his good spot neither. So more calculating GS, like Fed, and probably Djoker might start this method as well.
