. This blog (not mine) has some perceptive analyses about tie-breaks but the 'tie-breaks structurally favour big servers' hypothesis does not gain support from the myriad statistical evidence the author examines. It really irks me when TV commentators pull out this line, the perpetuation of myths isn't good for understanding a game.
Not sure about this. To me it makes sense the best servers would have an advantage. They are far more likely to win service games to 0 or 15, after all. In a normal set that doesn't make any difference as holding your service games is all that counts, whether it's to 0 or to 30. But in a tie-breaker, if you're less likely to lose points
on serve, that does
make a difference as the breaker is a matter of points. Of course you could make the same case about the best returners, but even in today's conditions, the serve is more powerful than the return, and the best servers win more points on serve than the best returners on return.
