Women players have so far been more successful than the men at challenging line-calls using the Hawk-Eye electronic replay. Four days into The Championships, and female players have been correct with 28% of their challenges, while the men have been right 26% of the time. What is more, women have been questioning the calls more often than the men, with 1.75 challenges per set compared to 1.70.
No woman has used Hawk-Eye more than former French Open champion Jelena Ostapenko, who has made seven challenges over the course of her two matches, getting two of them right, which equates to a 28.6% success rate. Lucie Safarova, a former French Open finalist, is among the small group of players with a 100% success rate - though the Czech has made just one challenge.
Since the summer of 2010, the prize money for the singles champions at Wimbledon has more than doubled, rising from £1 million to £2.25m this year. Over the same period, the price of a bowl of strawberries and cream has not risen by one penny, keeping steady at £2.50. This could be the only snack in London unaffected by inflationary pressures. And nor have the All England Club reduced the number of strawberries per serving - you're guaranteed a minimum ten pieces of fruit, while you can have as much cream as you wish.
In contrast, Eugenie Bouchard's new coach, Robert Lansdorp, provides a sense of how much things have changed at the All England Club. "My first Wimbledon was in 1977 when I was working with a 14-year-old Tracy Austin, and I was the only coach at the tournament. Just imagine that," the 80-year-old, who is back here for the first time in 20 years, told wtatennis.com.
While Serena is now addressed by the umpires as "Mrs Williams" - reflecting that this is her first Wimbledon as a married woman - her older sister Venus likes being "Miss Williams". The five-time Wimbledon champion thinks the 'Miss' before her surname gives her a certain class.
"I remember Janet Jackson had that song and she said, 'Miss Jackson', and I like that. I am Miss Williams," said Venus.
The song she was referencing was 'Nasty', which contained this lyric: "My first name isn't baby, it's Janet - Miss Jackson if you're nasty."
Williams, who has a pop-up store for her clothing range EleVen in central London this summer, has also been suggesting that she might be thinking about a future role marketing tennis players.
"I believe in tennis we can try to find a way to market our players better because that grows the sport," she said. "I happen to love branding. Perhaps I see myself in that sort of position after I'm done, or even now I think is maybe a good time to put into practice what I've learned from my businesses into tennis."
Talking of shops, one piece of good news for Maria Sharapova, who lost to a qualifier in the first round, is that her Sugarpova candy pop-up store in Wimbledon Village appeared to be doing good business when wtatennis.com visited this week.
