Rating System Broken.

I have had even winning streak of 16 games, my W/L ratio is above 1.0, but RD does not move from 45.0, meaning just 4-6 points per won game.

This is qute frustrating and so clear, that I do not see the point further to bring any other facts.

Getting about 5 points per games make a difference between 1500 vs 2000.

It is mathematically improbable to get 100 wins with 0 loss straight to get +500 rating. :)

Let's just double everyone's ratings.

The rating system is utterly stupid during a pandemic with so many question mark players. I am playing all day and have lost 3 points in 6 days. And I haven't been playing badly overall. Chess is ruined for me. I'm just coming here to spend another day feeling miserable.

@Aceno0b The only way to fix that is to lower beginning ratings based on player join rate. chess.com sees a lot more people joining so its beginning rating is 1000 or 1200 instead of 1500.

Now the way to prevent rating inflation is to simply remove the rating minimum: lichess.org/forum/lichess-feedback/can-we-please-make-the-rating-more-realistic?page=4#32.

I am a very good three check player and the rating system says that 6 days of effort by me are worth not one point as a reward, but in fact -3. Make any argument you like, that is just stupid, and there's no escaping it. I even tried playing 1600s today just to win some points...now I remember why I stopped playing them, a lot of them are freaking savage street-fighters...uuuuughhhh. Misery...

@Toadofsky "Let's just double everyone's ratings."

No, just make this rating system more realistic.

Indeed, on chess.com you have to earn it, from 400. Here you may lost 700 points very fast, but cannot gain it that fast again. That is extremely unlogical. I simply have no time nor will to play 100 games per day, nor I will have enough concentration to win it all. Few games per day is top I can play.

Seems like a lot of players are both too attached to internet chess points and also ignorant about how the algorithms actually work. Quite unfortunate.

@notzmv

Did you read and understand Glicko-2 documentation?

The main problem with Glicko-2 system is that involves probability and it is configurable. Slightly change in only one parameter may brings radical changes in rating, inhibiting further progress.

Implemented and configured rating system here is unfortunate, that is the whole point.

@n321 It's called rating deviation!!!
Lichess wants to make it so that your rating is guaranteed to be within a certain, small interval. If you have greatly improved all of a sudden, then you will gain points slowly with this rating system (if you had played a lot of games before), but this rating system still works about 90% of the time. chess.com and lichess have quite similar rating systems (they actually both use Glicko-2) - what you said in #147 is false almost in its entirety - you still only gain about 4-8 points per game once your RD stabilizes (meaning you have played enough games) in chess.com as well as lichess.

No rating system is perfect. @notzmv is right: it's a shame that nobody has even a basic knowledge of how these rating systems work.

BTW, don't tell me that FIDE is a more "realistic" rating system, because:
1) FIDE rating system has its own flaws.
2) FIDE calculates rating only based on tournaments.
3) Glicko-2 works in most cases, especially because leaving and rejoining as a much better player in a few months is not a common occurrence (well compared to the entire playerbase on lichess, nor is suddenly improving like crazy in like a week) and many people on lichess quick-match and/or use the lobby instead of lichess tournaments, making FIDE hard or impossible to use here on lichess.

Simply put, FIDE works in tournaments and Glicko-2 works for online chess.

Each rating system is fine tuned for its own purpose, but there is no perfect rating system, so there is absolutely no use complaining that the rating system is broken - the rating system is NOT broken, it's just not perfect. But please tell me if you found a better rating system meant for online chess (where people don't only play tournaments) and sure, I'll gladly ask the mods (eg @Toadofsky ) about it.
