National rating systems like the AGA uses have a more fine grained rating system, based on tournament results. It's not exactly ELO, because the AGA uses 100 rating points = 1 handicap rank, and of course it would a huge coincidence if 100 Elo happened to correspond to the win rate for one handicap stone at all strengths.
