Amateur programs with success in previous WCCC or WMCCC tournaments are better than those that haven't. Parallel versions of software running on multiple cpus can be expected to perform better than serial versions of the same software and serial software of similar strength. SSDF order might be used to sort serial versions of commercial programs. The goal is not to rank them perfectly. If that were possible, we might not even hold the tournament. The goal is to come up with a reasonable ranking for initial pairing decisions, and this is easily done. If 3 programs out of 30 are wildly misplaced, it isn't a big deal: the swiss system will take corrective action, as always. At the end of the tournament, no one will be able to claim that the winner played a bunch of weakoes. Dave
