Its not easy to find a weakness in Roger Federer, who is seeking an eighth Wimbledon title and an 18th Grand Slam triumph. Lets keep this between ourselves for now, but the Wimbledon Diary thinks it might have done just that.So far during The Championships, Federer has been successful with just 12.5 percent of his Hawk-Eye challenges, with just one correct query from the eight times he has called upon the technology. Contrast with his quarterfinal opponent, Croatias Marin Cilic, who has a hit-rate of 61.5 percent during the tournament to date, with eight correct challenges from 13 attempts. Of the eight men left in the singles draw, only one has a lower percentage than Federer -- thats Frenchman Lucas Pouille, who was wrong with all six of his, so is lingering on zero.In Novak Djokovics absence, Andy Murray is the highest seed left in the tournament, but he could also do some work on this part of his game -- he has been successful with 23.1 per cent of his challenges, with three from 13. The overall average for the mens singles so far is 30 percent, with the same number in the womens event, too.Golden Bear spotted in SW19Jack Nicklaus, who has been in the Royal Box for the past couple of days, is more than just a tennis fan. The golfer, who won 18 majors, has previously played some small part in tennis history -- the Williams sisters have been known to practice in the grounds of his Florida home. Nicklaus has three grass courts in his back garden.Serena aces the numbers gameAside from 22, which is how many Grand Slams Serena Williams will have if she lifts the Venus Rosewater Dish on Saturday, theres one number that fascinates her coach Patrick Mouratoglou. That number is 102, which is how many aces Williams served during the 2012 Championships. That was the first Grand Slam that we won together and she served at a higher level than I think anyone in the history of the sport, the Frenchman told the Wimbledon Diary. She served more aces in that tournament than any woman or man -- and you have to remember that the men would have been playing over five sets. Thats crazy. Her serve is just a huge weapon on grass.Passing the Wimbledon smell testUsed tennis balls can be bought from a kiosk outside Centre Court. No doubt a few tennis fans will be sniffing the Slazenger balls before using them at their local courts. Thats inspired by Slovakian Dominika Cibulkova, a quarterfinalist in the womens singles, who successfully identified a ball from each of the four Grand Slams on smell alone.
