RE: [computer-go] future KGS Computer Go Tournaments - two sections?

["David Fotland" <fotland@xxxxxxxxxxxxxxx>]

This is too hard since it takes a hundred games or more to distinguish
between programs of such similar strength.  No one has time.  I did a series
of 260 test games against handtalk once, and the 40 game moving average win
rate varied from 28% to 63%.  I tried using 20 game median score, but that
varied from -25 to +30.

The variance from game to game in computer go is huge.
