Just for fun, we’ve decided to give players in our Chess Eternament numerical ratings based on the English Chess Federation (ECF) system. Whenever you finish a game, you get a new rating based on your pre-game rating, your opponent’s pre-game rating, and the outcome of the game. (Results below.)<\/p>\n
<\/p>\n
It works like this:
\n0. Everybody who hasn’t completed any games yet starts with 100 points. When you finish a game:
\n1. Take whichever is less: your opponent’s pre-game rating, or your pre-game rating plus 40.<\/strike>
\n1. Take your opponent’s rating. If it’s more than 40 points higher or lower than yours, round it “toward” your rating so that it’s exactly 40 points higher or lower.
\n2. If the game was a draw, the number from (1) is your new rating. Otherwise,
\n3. Add 50 points if you won, or subtract 50 points if you lost.
\n4. If your new rating is a negative number, set it to zero.<\/p>\n
For those of you who like formulas, it works like this:
\nfor Rold < Ropponent:
\nRnew = min(Ropponent, Rold+40) – 50 + 100*n or
\nfor Rold > Ropponent:
\nRnew = max(Ropponent, Rold-40) – 50 + 100*n
\n(where n = 1 for a win, 1\/2 for a draw, 0 for a loss).<\/p>\n
