# Winning Wimbledon

In a (sudden death deuce) grand slam tennis match you must win 3 sets before your opponent, where the winner of each set is the first to 6 games, unless the score is 5-5, in which case you must win by 7-5 or if the score gets to 6-6, the winner is decided by a first to 7 point tiebreak (assume you can win a tiebreak 7-6). The winner of each game is the first player to 4 points (assume you you can win a game 4-3). Because of the rules of tennis, it is possible to win more points in a match and still lose. At Wimbledon, you must win 7 matches to take the title. Find the minimum possible percentage of points won to win Wimbledon, using the scoring system above.
