For instance, you may be a great strategic thinker, but prone to tactical attacks. Against most humans this will win quite often. But computers are merciless against the tiniest tactical faux-pas. On the other hand, my guestimate may be 500 points off. I really have no concrete proof. Your statement does make me wonder about it. Do you actually play the machine at 40/2 or at blitz or something in-between? It makes a super-enormous difference.
