If the purpose is not to encourage comparison then it is better to substract
10000 points from the elo of both programs when the elo of all programs will be
negative.

I think that the comparison is not unreasonable because the covariance between
the ssdf rating and the rating against humans is positive.

I do not say that the rating is the same but it is possible to get better
estimate of the rating against humans when we know the ssdf results.
