I was surprised by the number of tiebreak sets in the men's game, making up over a sixth of all sets.  Part of this could be because I only took data from Wimbledon and the US Open.  It would be interesting to see if that trend continued (likely not) during the Aussie and French Opens.  The men have much closer sets than the women, and probably due to the three set format, the winner of 90% of tiebreaks wins the match.  It would be interesting to see how that compares to men's 3-set tour matches.

I hope you enjoy this, please post if you have any comments and what you see in these stats.
