2007 was worse.
Chakvetadze got to #5 by playing like 38 mickey mouse tournaments
2004 year-end Top-10 included:
Davenport, Mauresmo, Myskina, Sharapova, Kuznetsova, Dementieva, Serena, Henin, Capriati, Venus. 8 Slam champions + 2 Slam finalists. 6 former #1 + 1 former #2 + 1 eventual #1 + 1 eventual #2
Also, Chakvetadze's slam results in '07:
QF, QF, 3R, SF
1) Henin: N/A, Win, SF, Win
2) Kuznetsova: 4R, QF, QF, F
3) Jankovic: 4R, SF, 4R, QF
4) Ivanovic: 3R, F, SF, 4R
5) Sharapova: F, SF, 4R, 3R
Hmm.. To me she has results as good as Jankovic and more consistent than Ivanovic and Sharapova.
The rest of the top 10:
7) Serena: Win, QF, QF, QF
8) Venus: N/A, 3R, Win, SF
9) Daniela: 4R, 3R, 4R, 1R
10) Marion: 2R, 4R, F, 4R
Anna's results are better than Daniela's and Marion's, and even with Venus's win Anna was overall better than her.
So, that means that Anna's grand slam results are as good as or better than 6 of the other top 9. So, by that logic she should've been 4th in the world!
So, yeah, I'd say Anna did a little more than "win mickey mouse tournaments." Plus she had wins over Jankovic and Daniela twice and one over Venus........
