I have played some games where people aren’t going up or down the normal elo, not to long ago I lost to someone and they gained 43 elo and this isn’t happening to me. Also I’ve seen people lose way more elo and this also hasn’t happened to me, so is there a new elo system or something or has this always been a thing and I’m just now see it?
The site uses the Glicko rating system and that includes a measure of rating uncertainty called the rating deviation (RD) value. Players new to a pool or that have a long gap in play will have higher RD values and see larger rating changes after games.
As more games are played that value decreases as does the magnitude of rating changes.
