 Yeah, if you win 54% of your points, then you have a 60% chance of winning the game, almost exactly 60%. And then similarly, if you've got a 60% chance of winning the game, you're highly likely to win any particular set, which requires you to win six games and to be two games ahead. And then if you're, I don't know, 75% chance of winning the set, then you're over 80% chance of winning the match. That's the kind of the way that the probabilities stack up.
