The purpose of a rank is not to give you a sense of identity, but rather to aid you in finding a roughly even game in a given environment. I think OGS does that well.
If you adamantly hold to being a 3k, but lose most of your even games, then maybe your “rank” is more pride than function.
If you adamantly hold to being 10k, because there’s just no way you’re strong enough to be SDK yet, but yet you win almost all your even games, then maybe your “rank” is more fear than function.
I think this thread may have a lot of behind the scenes overlap with The mind game - opponent's rank?
Though outdated, the message of this graph still rings true… attempting to compare ratings between unrelated pools is folly.
