Subject: Are CM9000 human personality ratings accurate for slower time controls?

I just read in the CCC archive that CM9000 personality ratings were established
at a time control of fischer 5/10.  Is that true for the human games CM9000
played as well?

Has anyone played CM9000 personalities at slower time controls?  How accurate do
they seem?

Back in the late 80's when Larry Kaufman was editor of Computer Chess Reports
the rule of thumb was to take a computer's speed rating and subtract 200 and
that would approximate it's tournament time control rating.  Should 150 be
subtracted in the case of CM9000 'human' personalities (fischer 5/10 is not as
fast as G/5, so subtract less) to better approximate tournament time control
ratings?


Regards,
