I came across this lady from Japan: https://ratings.fide.com/profile/7001800
She holds the WCM title, which according to the FIDE handbook requires that you have at one point in time reached 1800 elo rating.
However, her highest ever published rating is 1739 which doesn't even come close, so I doubt her live rating ever went above 1800.
The title was awarded in 2019. How is it possible for her to have this title?
Note: Nothing personal against this player, I'm just using her as an example to try and understand FIDE title regulations better.
