I've done some calculations
I hope they are right
Please check. But I THINK that after Luxembourg (Oct 10 rankings) Dinara WILL be top 10 no matter what happens in Luxmebourg.
On Monday 25th
The rankings will be
10, Nicole Vaidisova 1589
11, Dinara Safina 1541
12, Lindsay Davenport 1500
Next week Nicole will lose her Seoul points of 95 (her 18th result is 1 so a net loss of 94) and with Nicole not playing next week she has 1495 for the October 10 Rankings.
Dinara has 88 points to defend in Luxembourg but her 18th result is Paris QF of 49 points so a net loss of 39, giving Dinara at least (she can add points by making semi or better in Luxembourg) 1502 points for the October 10 rankings so more than Nicole.
If Davenport had gone further in Beijing she could have gained a top 10 spot but she lost in QF giving her 1500 points. Lindsay's points will not change next week but the week after will lose 220 for Filderstadt.
So even if Dinara loses first up in Luxemborug I think that Dinara will be top 10
