Thanks for the response.
What I noticed was that starting a game in, for example, 2009 you still have players such as Wan-Ting Liu, Holly Parkinson, Andrea Herran etc near the top of the rankings all of whom either never had a high ranking or had retired at this point.
Also there are some players who still have wrong ages that I think should be updated. For example, Katernya Bondarenko, Alla Kudryavtseva, Yaroslava Shvedova, Mariya Koryttseva, Melinda Czink. All who have are/were around top 50 at least.
I understand it is tedious and time-consuming updating the rankings, but it would be nice to see them updated more, because at the moment they are still pretty unrealistic for the last few years.
