Yeah, that rule is terrible for low ranked players who play WTA/ITF through the year. Out of her 17 best results for the rankings Kimiko had at the beginning of the year these stones on her back
5 pts Australian Open
5 pts Miami
5 pts Roland Garros
5 pts Wimbledon
5 pts US Open
5 pts Beijing
Now for instance her 18 points for Limoges last year are not counted in her ranking
And we can say she is lucky in the sense she had a lousy spring/summer, otherwise she would have all these 5 points while several 30 points not being counted...
