The WTA rulebook page showing points doesn't allow for 48 main draws. But it is 9 points for QF, then 18 for SF, 30 for F and 50 for the title.
ETA:- The ITF table does allow for 48 draws, but the points are as above
Would be great if Katie could add 50 points on Monday week to effectively replace the 50 points that are coming off on Monday and so preserve her ranking points over the two weeks. But a bit to go yet.
