There is written: "If you don't play ELO for a few days your ELO value will slowly go back to 1000" in rules. What does it mean "a few days"? Does it mean that it will decline after one, two or how many days? And how quickly does it return to 1000? Thank you.
Your ELO goes down by 2 for the first day you do not play ELO for the first day that you play. E.g. you have 1210 ELO, don't play for a day it goes down by 2, don't play for a second day it goes down by 4 so if you didn't play for 2 days it would be 1204
