BCRS Tournament Rating Formula

For every game in this tournament, the rating a player had before the tournament is used. As this is the first BCRS tournament, all players start with 1500 rating points.

Rnew = Rold + K × (S − E)

All players had the same starting rating in this tournament, so each player’s expected score over 9 games was 4.5 points.

Change = 40 × (points scored − 4.5)
Note: This is a tournament-based calculation. Ratings are not updated after each game, but only after the entire tournament has finished.
