Not that I’m complaining. Chess level 2 is probably where I belong now. But last time, I was in level 4. And I didn’t think that’s how it works. It doesn’t look like too many players dropped out, either, as there is still a well-populated Level 4. And I’m one of 10, not 9 players in my section. Is there some rule that moves one up multiple levels if one’s rating is high enough, creating an extra spot in a section?

I had a similar experience 2 years ago. I won a  EWN level 3 group, and next I played in level 1. Maybe it has also to do with your actual rating?

Anyway I am testing it right now. Playing at level 4, trying to keep my rating well above 1800. See what happens next ;-)

I think if there are empty spots in the championship there are filled based on rating.

Dvd, maybe you could ask Richard in your chess game ☺

Good idea.

Good idea.

He was also my first opponent here, way back in February, 2003.

Richard explained that if your rating is higher than the average rating of some group above where you’d otherwise be--and if your last finish in a championship section wasn’t last place— then you get placed in the higher group. I vaguely remember when he made that change, but had forgotten that it applied to levels below the top one.

Thanx for explaining Dvd :). Then it was a good idea for me to stop playing those 1-point EWN tournaments, they give the risc of very fluctuating ratings (maybe Richard should use a different algorithm for rating changes for 1-point EWN games?!). Now I have a chance to promote from level 4 to 2...

And yes! Now playing at level 2 of the championship! :-D

I back up another rating constant K for Ewn 1-point games, I tried not playing them any more because I don’t want a random fluctuating rating.

Any math geek can propose a right constant?

In this thread: https://www.littlegolem.net/jsp/forum/topic2.jsp?forum=140&topic=183,

YHW used K=3 and Darse K=4, saying "The B-T column is the Bradley-Terry rating with a K factor of 4 (one eighth of the value used on Little Golem). That means a player winning a game against an equally rated opponent would gain 2 points instead of 16. However, K = 4 is still too high for satisfactory stability."

In multi-game matches, it would make sense to vary K proportionally with the square root of the number of games.

It also would make sense to use the result of the game rather than w=1 for a win  w= 0 for a loss in the formula.  If I win 5-2 it would mean w=5/7 for me and w= 2/7 for the opponent.
