Rohan, right now I am busy in reasrch about new method which I think it will be most easy to predict winner, by chinese astrology and 5 elements chart. I have one idea and have to check out it in some examples, but I need time of birth for persons in play.
About Nadal, I write to "QandA" section on his official site and now wait for answer. I also did it on official site for Djokovic requesting his birth time.
About final match of US Open, it was easy, Moon was VOC (Federer in almost every final match has lucky to have it!) so favorite, Federer ,wins.
I did not coment matches, because I do not know what color kit player will wear. But if you want to predict winner you can do by horary chart 1st against 7 house ruler, same as for football ,and when match begin you will know "who is who" by colour kit and you will know who will win.
