I get different answers from different sources and really just want all the rules of ELO Decay with 100% accuracy. These are the the things I need covered.

  • How long (to the day) without playing a Ranked game does it take for your Elo to decay?
  • At what percentage does it decay?
  • If you play a ranked 5v5 does it reset the Elo Decay timer for your solo queue?
  • At what Elo does your Elo have the possibility to decay?

If your ELO is under Silver (1400) then you are unaffected by ELO Decay. Ranked 5v5 runs on a separate ELO system from your solo q ranked ELO from your normal ELO. from your 3v3 ELO. So anything you do in one does not affect any of the other ELO numbers.

Not sure of how long precisely, but I've heard it's 1-2 weeks you have to play a ranked game. It decays a flat amount rather than a percentage.

I really would like an exact number or weeks for each queue. I don't understand why they have something implemented but no official explanation. – GGClassic-Jona52 Mar 25 '12 at 23:55
Do you have any sources? – Dante Apr 21 '12 at 0:38

Elo decays over time when you are above 1400 after 4 weeks of inactivity at a rate of 25 per week in that particular queue. Each queue is separate so you have to play a 5v5 match to avoid decay in your 5v5 rating. It won't decay past 1400 rating.

Has this been tested or do you have any links or sources to verify? Thank you =). – GGClassic-Jona52 Apr 1 '12 at 6:49

Elo decays after four weeks of activity in a given queue once you get above 1400 Elo. You lose 25 per week after that.

I read from a red post that it takes about 4 weeks of inactivity in ranked games.
