1800 is gnugo, so this puts top programs near 1k (2d for extreme mogo_18) this seems reasonable to me. Im surprised when i compare this scale to http://en.wikipedia.org/wiki/Go_ranks_and_ratings Obviously there is a factor 2 between both ratings scales, (as i don't believe mogo_18 is 9d EGF ;), but this is just not important, as far as we know it.
