You already reported 75 ELO improvement. Gelly said you should get 200-300. So you are only about 125 off of Gelly's lower bound (which sounded like a rough guess to me.) So you have a lot of uncertainty here and only 150 games. Of course this is plenty enough to suspect a problem and investigate, but it's not enough to conclude that you surely did something wrong. How much did you test the version that doesn't have this change? You have 3 sources of slop here: 1. Gelly's rough estimate of how much you should get. 2. The rating uncertainty of the unmodified program. 3. The rating uncertainty of the modified program. - Don _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
