Differences in the Two Elo Systems

Assuming that you read my last post about updating the MLS Elo Rating system, you’ve probably been on the edge of your seat waiting for the revised end-of-season ratings. Well, here you go!

The big difference is that, in my opinion, game results (win/tie/loss) were being heavily overvalued against goal differential, especially for playoff games. 10-15% of the games were having way too much effect on the overall end-of-season ratings that should be based, at least somewhat, on all 30-something games.

I’m much happier with the balance between the two now.
