Thank you, didn't think about a difference in the "constant" between humans and
computers.

While I was disappointed that the opening book is smaller than originally
planned, and I think the ROM (or RAM) is smaller than originally planned, I
still consider it a good deal.  My previous dedicated is a RadioShack2150L,
about 9 years old.  The RS2150L computer gives me a good game at level A6, in
which the computer averages 1 minute per move (and not 40 moves in 40 minutes,
but average response time of 1 minute per move).  But I don't like waiting that
length of time given that some of those games get pretty long.

***REALLY?***

This blows me away.  I really can't fathom that at 2 seconds per move it's rated
1725.  Or at only 5 seconds it is a Class A player.  Do you really think so?
The lower levels seem awfully strong.  I know you are following the
log(speedup)/log2 *75, but those estimated ratings at 2 seconds and 5 seconds
really seem too strong.  But I have no proof to back up my claim.

My personal opinion is the same, SSDF=USCF at the moment
