After a posting from you about a week ago, I have been meaning

We do not restart MFGO between games. We set the internet play
to accept all matches and roll over from one game to the next as
soon as a game finishes.

This may explain why some of our clusters get different results than
others, although by now I might have guessed that they would have
converged after a few hundred games.

I intend to go back thru the game records and see if the winning
percentages are greater with one particular opening ... but it has
been hard to inspect them all. Maybe it is time for a perl script.
