Re: Laura Robson: The Silver Medal Years 2012-
Just to give an overview how it looks these days when it comes to her ranking (Spoiler: Not great.). She'll basically have to start from scratch.
As she has a PR she'll get into the Aussie Open and she's guaranteed a WC for Wimbledon, so the big goals for 2015 will be to get into the main draws of the other 2 slams.
The 3 "/" tournaments are free spots in her ranking, i.e. she hasn't played a tournament that could count towards her ranking, but the zero pointers from Indian Wells to Wimbledon will stay in her ranking until they come off.
