Subject: How close/accurate will the rating be in a 10 game match?

Hi,

If two computers, one with a known rating and the other without a known rating,
play a 10 game match, how close/accurate will the rating of the unknown computer
be?  Based on some rough mathematical modeling I've done based on SSDF results I
am guessing it would be about 200 points.  Does that sound about right?

A related question:  The most common rule of thumb that I have found in old
issues of CCR is that a doubling (or halving) of computer thinking time (with
thinking on opponent's time turned off) is worth 75 points at the USCF expert
level.  Is this still a valid rule of thumb?

Thanx,

Kerry
