Yes, it was ruined at least five times I can recall in last years, now its ruined again, accept it, your man cant always be on the side that is favored before the final.
Naah. It's not about Federer or Nadal or Fedal. I have always been against Saturday matches for men. Unless they start like 6 AM, someone gets screwed.
Besides, the quality of final will be much lower if these matches go long. Usually they don't, if you look back. But when they do, someone's dead tired.
