RE: [gnugo-devel] strength against Many Faces

[David Fotland]

flearn9 is for 9x9 games.  flearn19 is for 19 line games.  It keeps a
separate database for each board size.

Are you sure you are checking the modified date and not the creation date?

If you have several PCs running mfgo, then the learning is not being shared
among them, so you might see
repeated games played on different PCs.
