It is usually possible to gauge how hard Maria Sharapova has had to work by multiplying the decibel level of her shriek with the combined total of C'mons and pumped fists. Yesterday, she barely had to get out of bed.
Even though her vanquished opponent, Elena Dementieva, complained about the volume of her grunting during their Centre Court encounter, the world No 8 would only need to have heard Sharapova in the previous round to know she got away lightly.
Sharapova was taken to three arduous sets by Flavia Pennetta on Monday and it is probably not overstating the point to say, win or lose, the Italian would have been relieved to put more than a tennis court's length between her ringing ears and Sharapova.
By the standards of those otherworldly emanations and considering the fact that Dementieva was not around that long to be too bothered, in that respect at least - Sharapova, who won 6-1, 6-4, was pretty merciful.
Dementieva didn't think so: "I think it is a little too much," she said adding she felt there should have been an official intervention.
"I think the umpire should calm her down a little bit. When I'm on court, I'm trying to be focused, it doesn't bother me, but I think it's too much."
In response, Sharapova claimed that it is only ever in this country that she is questioned about the noise. She was unrepentant: "I don't worry about that. I wouldn't change a thing."
Unlike the streaker who interrupted proceedings in the second set when he changed out of everything and frolicked around the most famous court in tennis before running compliantly to the waiting security guards.
Sharapova turned her back and ignored the intrusion but wondered why the interloper was not removed more quickly.
"It was bizarre," she said. "It took ten seconds for security to come out. I looked at them and they were laughing. Then they took out these blankets; they must have been prepared."
As was Sharapova. The 19-year-old produced the best performance at this tournament since she dismantled Serena Williams in the 2004 final. To ape her received Floridian parlance - she was awesome.
The No 4 seed was ruthless with Dementieva's patsy serve which struggled above 100 mph with a tailwind and averaged out at a mere 96 mph. When the former US and French Open finalist dropped her second serve speed down to the low 80s - as she did on several occasions, the ball was veritably splattered back before she could respond.
Sharapova broke her four times in all, twice in each set and rarely allowed her compatriot a platform from which to demonstrate her own dangerous groundstrokes.
When the ball was short, as it tended to be midway through the second set, Dementieva was able to club a winner on either wing; more often than not, it was spitting up at her from the baseline.
Sharapova saved a break point in the first game and went on to break twice before serving out for 6-1 in 27 minutes.
She took the Dementieva serve in the first and third games of the second set, teed up a 4-0 lead and looked primed for a routine victory. She closed out with an unreturnable ace - her 20th of the match - to book a semifinal with Amelie Mauresmo.
The world No 1 put in an inconsistent performance against Anastasia Myskina but eventually prevailed 6-1, 3-6, 6-3 to claim her fourth consecutive last-four appearance at the All England Club.
She appeared to have brought her dominant form of the first week into the quarterfinal but, after overpowering Myskina in the first set, her forehand began to break down and it became a match that would be lost rather than won.
Myskina broke in the second game of the next set and held her nerve to cling on and Mauresmo claimed the only break of the third to go 4-2 up. Although she wasted a match point on the Russian's serve, she was able to claim her place in tomorrow's semifinal in the next game.
