I understand what you mean but the credit goes to two persons who happened to be the right partners for each other and they do have to be in fine form at the same time to succeed, so in a sense it's a different ball game from singles, almost like comparing apples and oranges. That is, in singles, win or lose, it's one person's business.Doesn't this make doubles harder? It's harder to get 2 people in form than 1.
