Here I'm not really invested in any of the numbers... the website is beautiful though.
Then, the probability of player 1 winning a set 6-0 is p⁶; the probability of player 2 doing that is (1-p)⁶.
Let’s assume a fairly evenly matched game, where p=0.6. Then, those probabilities are about 4.7% and 0.4%. Combined, that’s about 1 in 5,000, or 1:2500 to get either of 6:0;0:6 or 0:6;6:0.
Doesn’t sound too bad but in real life, that number will be a lot lower because of the server advantage in tennis. Especially in men’s tennis, the server has a big advantage, making even single set 6-0 scores highly unlikely.
In the Women’s 3-set match, where there are 735 possibilities, these scores have never eventuated:
6-0 0-6 7-5, 6-0 0-6 6-0, 0-6 6-0 7-5
Meanwhile, in the 5-set format of Men’s matches, only 8.5% of the more than 100k result possibilities have occurred.
Then add on a huge UI.
