Federer picked up 640 ranking points on the blue stuff in Madrid, and Djokovic lost 820 ranking points. The current difference is 75 points, so strictly from a mathematical standpoint Federer would not have risen to no. 1 in the rankings. I apologize if this is a dumb thread, because after winning Wimbledon I suspect that Federer would have gotten there eventually. But it puts more emphasis on the Madrid blue clay fiasco. He was extremely fortunate for that surface change, and you might even say that he's lucky to be in the position he's in now. Federer has won the Madrid event before, but I wouldn't have picked him to beat Djokovic and Nadal consecutively like in the previous year on the red stuff. I know there are a lot variables in tennis, but usually that's not a surface change to something no one has ever played on.
