Every number may be wrong because the performance of programs against humans may be different than the performance against computers. I also read that there was a noise in the match against Hiarcs6 and one match is also not an evidence. I believe that if you do a match between humans with 78 points rating difference you will find often 4:2 results for the player with the lower rating. I am sure that you can find examples in the ssdf games when program A won the first 6 games 4:2 inspite of being more than 78 points lower based on the ssdf rating. Uri
