OK, now if I used Crafty for analysis of Fritz or Rybka games, it would
certainly not agree and would often call their moves 'errors' even though
they are FAR stronger than crafty.

To properly analyze the world champions
you would need to use a program that is atleast equal in strength to
these champions. Crippled Crafty just doesn't cut it... now if they
used Rybka for analysis I wouldn't have any problem
with the study.

Not true at all. Crafty could easily tell you which programs far
stronger than itself played the most perfect chess. This is not
debatable. For instance, the winning program between two chess
programs playing each other by definition will produce at least one
less error than the losing program--and Crafty could, at some point,
appreciate this.

The only way you can get around your erroneous statement is to qualify
"properly" in "properly analyze". If you mean that it is better to
have an even stronger chess program than Crafty to better ("properly")
rate the champions, of course you're right and nobody would disagree
with you. But that doesn't mean Crafty's efforts are of no value.
Perhaps with a 'properly' written program you might have, in a close
tie, a switch between two players say tied for fifth place in the
pantheon of all-time champions
