GNU's ELO Ratings

GnuBG's ELO rating is an "estimate" based on an independent weighting of the Cube and Checker error plays. It isn't always accurate. I find less so in shorter matches. It's possible that the higher ELO for the higher error rate is because of the way the errors were distributed (between checker and cube error rates) for both players.
There is a paper on how the calculation was arrived at here: http://www.cs.ubc.ca/~kvdoel/tmp/ratings/
