When I added the 40 games to the database and clicked on "Create >ELO Start List" to my surprise, Fritz was rated higher than Junior. (...) This sounds surprising to me also at a first look. But there may be an explanation: If you let calculate a starting list, every player's rating is set to 2400 at first - but there is a minimum of games for a player to get rated I think. If some of Junior's opponents, from the earlier games, didn't reach this minimum (or had very low ratings), then it's possible that Junior therefore gets a low rating himself. His opponent's average may be much lower than Fritz' in your database. I would try the following: Make a database like it was before (without the Fritz 6 games), and make a elo starting list. Set the resulting ratings into the games (menu item "set elos in games"). Add the Fritz 6-Junior match to the database. Mark only these new games in the list and choose "add to elo list". I did not simulate this whole process on my computer, but it should take the former rating of Junior as a basis, although it could be reduced a bit if the percentage is lower than before. Please backup everything before you try... Regards, M.Scheidl
