You make valid points about bias due to playing styles and
holes in the knowledge/skill. But that still doesn't invalidate
the point, you were supposedly arguing against, that from the
small number of games a good human player will extract much better
judgment about the player's strength than the mechanical rating
calculator.

After all, in your game example, you knew after a single
game what the weaknesses and strengths of your opponent were and
you rated his strengths in different phases. Yet the mechanical
rating calculation from a single game (or even a handfiul of games)
is useless.

Similarly, if you analyze and think through a game against some new
program, even after a single serious game you will have a fairly
good sense on how strong it may be. At least against you. But the
exactly same caveat 'strength only against you' applies to the rating
calculator, too. The key difference is that after a single or a few games
you'll be able to predict the future scores of the program 'against
you' much better than the mechanical rating calculator. You have
extracted much more info out of a small number of games than the
rating calculator which counts only the final score.

In conclusion, it is either out of malice or the blissful
ignorance (or even malicious ignorance) that some folks ridicule
Thorsten (and others) for making claims about the program
strengths which would clearly be unfounded if one were merely
calculating the ratings from the same small number of games.
