Good question, Marc. A well-formulated attempt to get a straight 
answer. But you won't get a straight answer. :-)

My finding with Maven was that some players could defeat Maven at far 
above their expectation according to the rating system. And some were 
far below.

In those days a rating of 1800 was about 300 rating points lower than 
the peak human rating. Such a player should have ~10% chance (?) of 
beating Maven at the top level (which was non-simming in those days). 
Yet I know one 1800 player who was able to win almost 33% of her 
games.

I know of two winners of multiple world or national championships 
whose tournament ratings were comparable, yet one could beat Maven 
49%, and the other was around 35%.

BTW, there are several hundred games (over a thousand in some) in 
each of these samples. Maven would keep a record of every game that 
you played, so I was sure that the differences were real.

It seemed to me that the players who like to keep things wide-open 
were at a disadvantage. That style probably helps them in their human 
games, but it is a problem against computers.

None of that ever bothered me, though. People wanted to know how 
strong Maven's levels were, so I gave them a straight answer. I just 
set the top level to 2100, and calibrated successive levels at 50 
rating points lower and lower. Based on self-play.

This system does not guarantee comparability to human tournament 
rating. Possibly the Quackle developers can devise a technique that 
is comparable. Still, individuals will vary from that baseline 
depending on their style.

Best,

SOWPODS.
