Source: Robert Jasiek on GoDiscussions forumJapanese male:
Usually the strength increases with the rank, although there are relatively weak or strong 9p's.
Japanese female:
A female player of rank x is, on average, significantly weaker than a male player of rank x.
Korean male:
To exaggerate a little, ranks have no meaning.
Korean female:
A female player of rank x is, on average, significantly weaker than a male player of rank x. High ranks are stronger than low ranks.
Korean versus Japanese:
On average, Korean male is significantly stronger than Japanese male.
Chinese versus Japanese:
For below top level players, Chinese is a bit stronger than Japanese.
So, don't think that all dans are the same. For example, male Korean 1p is usually stronger than average Japanese 9p and it's not a sensation at all.
