If Kvitova wins the title, well even if she doesn't, what will be her ranking?

Well, since she made it to the semis last year, she won't be gaining that many points. If she loses, she will actually remain at #8, and if she wins. She currently has 4337 points, she is defending 900 points from last year. Since she got to the final this year she will get 1400 points from Wimbledon, so 1400 - 900 = the total # of points she would get. If she wins Wimbledon, she will gain 2000 points, minus her 900 points from last year, which would give her a total of 5437 points, putting her at #7, jumping ahead of Schiavone.
