Where did you see that? The only statement I ever saw Joel make was that when asked how he did against DB while working on the book, he said "it killed me badly" or something similar. This was at a press conference in NY during the second Kasparov match. I don't think _any_ GM scored 60% against the thing in any match ever played against it, or deep blue junior...
