I beat a 2501 and drew a 2433 and languish at 2408?

Surely you are not carrying over the 2008 ratings? :)

At the end of 2008, you were 2370. Standard deviation was 75.

First, you beat Mikhailuk (2488) with Black. That's an effective rating difference of -190 (2370 - 2448 = 118 - 72 bonus for having Black). As a result, you went up to 2442.

Thenm, you drew Kaufman (2398) with White. That's an effective rating difference of +116 (2442 - 2398 = 44 + 72 penalty to having White). Also, since Arizona lost that match, the draw is counted as 0.33 insteas of the usual 0.50. As a result of all this, you went down to 2408.

Should you like to look at the spreadsheet, please let me know.

Did you invent the sadistic set of penalties all by your lonesome?

Bionic Lime said...

Arithmetic invented them.

After analyzing (statistically) all USCL games, it came out that White offered a 72 point rating advantage when it came to expected score.

Then, the 1/3 score if you draw when your team loses, and 2/3 score if you draw when your team wins, came from the logic of team play, when match points are all that matters.

The rating system is based on Glicko. And, I passed the variations by Mark Glickman, chair of the USCF Ratings Committee.
