There are two major attempts at international ratings today. Dr. Bae Taeil does ratings for Korea, and Remi Coulom produces ratings independently, based on the database at go4go.net (<a href="http:&#x2F;&#x2F;goratings.org" rel="nofollow">http:&#x2F;&#x2F;goratings.org</a> is the site).<p>Taeil&#x27;s method seems unusual, though it may well be justified . I think he&#x27;s using a relatively complete database of games, but I don&#x27;t know for sure. Coulom has a very well regarded mathematical model, but we know that there are some gaps in the database, which a) may skew international comparisons, and b) may result in inaccurate ratings for players with few games in the database (but those players are usually not top players in the world).<p>See my comment below: there are very few 1p players near the top, unsurprisingly.
