Well here is another update:
If we take away Capriati's points she is dropping next week, it'll be:
If Venus wins her semi-finals later,
If Venus wins the title over Henin,
We will have a new number 1!
How long Venus will hold the ranking will depend on her performance at Dubai. If Venus wins Dubai, then she'll probably hold it till Ericsson Open. Then, if she wins Ericsson Open, then it is very likely that she'll hold the ranking till Wimbledon as she has so little to defend meanwhile.
But she MUST win Dubai to hold the number 1 ranking for a long period of time as she is dropping 174 points for Indian Wells. So she must do well at Dubai to make up for it.
Winning Ericsson Open is crucial too... she has 443 points to defend there! So that's 617 points to defend compared to 393 for Jennifer.
Hence, to make up for it Venus has to win Dubai or I don't see her holding the number 1 ranking for too long. Should Venus lose the number 1 ranking, she should gain it back during th clay court season. Capriati has 696 points to defend before RG and 1646 points to defend if you throw in RG. Venus has just 308 points to defend after Ericsson Open, so you get the idea
