Normal expectation was that Sandro just tried something and cried Ura after some statistical noise as well as that observing behaviour in a few test positions does not tell something about playing strength. So CEGT data confirm the to be expected results. :-) Joachim P.S.: I recommende testing threshold=50 since it is for us interesting to know the behaviour of lower threshhold in longer games - I never expected them to score better.
