When are the restrictions coming down ? Is it at her 17th birthday, in 12 days ?
As a 17 years old, she will be able to play 16 tournaments + 4 merited increases(getting directly in the main draw or qualifying of Grand Slam and mandatory tournaments). You can only use 2 merited increases for the Grand Slam. So in short she will be able to play about 20 tournaments form her 17th birthday until she turns 18
