why did my Puzzle rating go down by 1000 elo
maybe in the settings, the fourk between the minimum and the maximum of your problem's elo.
I don't know exactly if it isn't this...
Same thing happened to me. I do puzzles basically every second of my life, but my rating seemed to go down. Not sure but I think that happened😟.
last week my rating in puzzles was 2700 and now it was go down to 1700 elo
Isn't it concerning???
