The use of statistics has become increasingly prevelant in predicting sports performance. It is pretty easy to build a spread sheet that accurately predicts performance in football games and baseball games. (the models give you average scores and win percentage).
In tennis, the most accurate predictor is simply the percentage of overall points won (you can break it down further into service and returns).
Last year at Wimbledon, Federer won the match and beat Nadel by a total of 7 points out of 400. This year Nadel won the match and beat Federer by 4 points out of 400. Most math guys will tell you that both matches were statistical dead-heats and the winner won as much by luck as anything else.
In otherwords, did Nadel have Federers' number, or are they equals on grass and Nadel got lucky this time?
