I think that the score calculation should be slightly different. It's Glicko, isn't it?
The changes should appear in matches, for example 5 games match:

Now if you win such match, you gain, let's say 20 points.
But you all agree that winning 5-0 is more valuable than 3-2, isn't it?
Could the scoring system be modified, so that the winning player would gain score adequate to his result in the match, not as in single game?
Example:
I win 7-4 in a match. normally, Glicko calculate would my new score, so I'd get 20 points. (let's keep it simple) But since I've won 7-4, Glicko's result is multiplicated by 7/4, and therefore I recieve 7/4*20=35 points. On the other hand, my opponent loses 7/4*10 points, which means his/her score is down 17 points.

In case of winning 5-0 (5/0's absurd) we could use 5/1.

No, it's not. It's neither Glicko (which would take into account how recent your rating is - if you've played a lot recently, your rating will change much less (aka, is more stable) than if you haven't played a lot recently), nor is it even Elo based (which does account for how big the score was in a match - with Elo, you can actually gain rating points while losing the match: for instance, if the rating difference say you ought to lose the match 7-3, but you only lose 6-4, you win rating points; the winner of the match looses points).

What system BK uses, I do not know. But based on observations how rating points are calculated, I can say it's neither Elo, nor Glicko (note that Glicko also takes into account which how many points a match has been won).

I don't know scoring systems much, but it can be some glicko modification. (I play a lot of line4, and now my score changes vary from 4-25 when my opponent is 2000 or 1200 - my score is 2100)
My idea is still active. Pleas state your opinions.

Teachme2play: It's not Glicko. Your rating doesn't change much because you have played a lot. But if you now stop playing line4, wait a couple of years, and then play again, your rating will still not much. BKR considers a rating well established if you have played a lot of games. It doesn't distinguish between having played those games in the past month or five years ago. Glicko does.
