How many fuckin times are you going to paste this onto someone ' s comment ? We get the set up now . <| sep |> Black people gon kill you <| sep |> 211 hereVivi dupeAshe finally has her clothesConsidering I got OK BSB first try I ain ' t even mad <| sep |> I believe I read that it ' s for acoustic dampening during launch . <| sep |> I have studied Bayesian probabilistics so i have some insights about these models such as TrueSkill , i actually went very quickly in some of the scientific papers from Microsoft . But yes you can send the articles if you think they bring some value . The example you gave me makes me think you are misunderstanding the main idea of the algorithm . MMR is not just a question of winrate alone as you pretend , it ' s a question of the MMRs of players involved in game uncertainty for the variation . If the MMR has been normalized what are the original values you are talking about ? They don ' t matter anymore . It ' s just a way to compress a bit the differences . There is maybe a new mean but it should not , maybe a new rule for the variation more probable but it doesn ' t matter that much . The only effect it could reasonably have is that you may be matched with higherlower differences of skills but this has NO DECAY EFFECT on your own MMR . A decay in our context is a function of time delta MMR . You can extrapolate on side effects of the normalization but it ' s NOT a decay so don ' t call it as such .
