I'm not sure what you mean by "favoring"
I don't mean "favoring" in a negative conntation, but the fact that, since very many more higher rated players are men, and the FIDE rating average include more higher and less lower rated players than women (although there are many players, men and women, lower than 1500, maybe the great majority - these players aren't really represented.), there might be something going on that isn't reflected on the surface.
I'm not sure what you mean by "favoring" -- I wouldn't assume FIDE is trying to discriminate or anything, as obviously they will take a man or woman if they meet the requirements -- I'm just saying their data doesn't represent all tournament players, but mostly just the more experienced ones. Among less experienced tournament players men and women may or may not be equal -- I don't know the data.
