Rating formula in lichess changed?

@miretota How do you know the number of players hasn’t gone up? As in your original thread, you are contradicting yourself: you say there has been a “flood of strong new players”, and now you are saying there is not a significant number of new players. Which is it?

If the 6000 people have surpassed you because of some rating inflation that you have failed to describe, then why hasn’t your own rating similarly inflated?

@Chuck_Fess
You can see the number of players and of the games in progress. As I said before, this number has always been growing constantly and slowly, I can't see a big jump in the last time. And I never made a statement, I asked questions, because a few weeks ago there was this strange thing with the rankings. I mean it could be that in the last time lichess attracted especially titled players, for whatever reason. About my own rating I can't say much, as I play only very few games. It was a general observation about ratings and rankings. I had written down some ratings plus their rankings and followed the development. As I said - changes were slowly. And now all of a sudden a huge jump. I have no idea what has caused this, I'm just asking.

It seems to me that there is a rating inflation in bullet, but I'm not that sure for blitz.
I think this has begun with the launch of the titled arenas. Not sure there is a link though...

"Not sure about the number of players, but the total number of games played on Lichess has increased dramatically over the last year:

database.lichess.org/"

This must be it! Such high amount of players increase they must register and lose their rating points for some reason. Maybe someone doing it intentional for some reason, maybe lots of newbies joining that are below 1500. Maybe rating 1000 - so they lose 500 rating each to higher ranked players.

Even this explanation has shortcomings. If look at database size it has been groving all the time. Secondly G2 algorithm is not zero sum. If a newbit is about 1000 he will get provisional 1500? rating and lose to established 1500. the newbie loses something like 240 points and established player gains about 6 points. then on second player loses about 200 points and alreasy has his/her rating at roughly correct range.

In this process newbie contributed about 12-16 points to pool. That less thatn 20 point divided on huge pool does not mean much. You woudl need amount of newcomer equalling established players to make less than 20 points inflation.

Further more as these players get established rating and start learnign they would win back those point from pool

I would say (assuming the jump is real) we still dunno why.

I noticed the following:

-playing a much lower rated opponent with an active account yields you close to nothing (+0, +1)
-starting to play with a passive account which was idle for say half a year you‘ll gain much more, probably factor 3 or even more (+6)

I played three lower rated opponents (-400) and gained +15 with an old account. Impossible with a recent active one.

@CM Sarg0n

That's because your rating deviation increases automatically over time if you are inactive. In other words, it's not a bug, but a feature. The goal is to re-adjust your rating quickly within the current rating pool, if after some time of inactivity here your skills deteriorated or improved.

Thanks CM Sarg0n...Now I understood why even i doesn't play some format...My play curve is stable continuation...Up to now I thought it is my phone problem...
