You are right Sim, Heather will already be provisionally GB doubles no 1 and would have slipped ahead even without taking Joss / Anna's Sunderland points off :
Heather : 673 + 130 ( Aus Open R2 ) - 1 ( existing 11th best ) = 802
Joss / Anna : 796 - 50 ( Sunderland 25K title ) + 18 ( existing 12th best ) = 764 ( which might be tight for staying in the top 100 )
I think when looking roughly I had added R2 singles ( 70 points ) or just couldn't count !
240 points for reaching R3 / L16 would take Heather to 912 points.
I note, with the Fed Cup coming up, that after a very productive summer Joss / Anna have only had 5 ranking matches ( 1 win and 4 losses, albeit all but one WTA tour ) and none since the end of October.
For fans of the WTA in general, and obscure facts and stats, they have just released a 226 page (I kid you not!) set of match notes for tomorrows match ups. It actually details most of the players and matches at the AO to date, along with reams of miscellaneous stats at the end.
I wonder if this is the sort of thing they produce regularly, and is reserved for the press.
