(Of cource with "pretty good" he could mean "bad", but i don't think that). And moreover he calculates a rating for the chess engine called: Shredder! That means he combines the performance of different Shredder chess engines: Shredder 6/6.02/.../7 for having an ELO of Shredder. Although one can say this can be done, if we think Shredder as a person with learning ability, like a human which improving along the years, but i disagree and i find this dubious, as Shredder 7.04 is totally different to Shredder-6.
