Your example shows exactly that you are considering MMRs to be absolute values , not relative values . Player A and player B . Both have 3000 MMR . Season 1 roll comes along . Both players are now at 2350 MMR with high volatility . A rescaling just means that 2350 is the new 3000 . The value in itself DOES NOT matter . What matters it the value compared to others players . You could say 3000 becomes 1 and 1500 becomes 0 . 5 . Player A remains active , and within a few weeks , the player is back at 3000 MMR . No , you are wrong . He will stay around 2350 if the rescaling says that 3000 becomes 2350 . If he goes up , it ' s simply because his skill improved . This has nothing to do with the algorithm at least theoretically . Player B doesn ' t remain active . In a few weeks , the player will still be at 2350 MMR . And so ? The players under him shifted as well under him . 2350 does not mean bad , it means the same as before with a different scale . The old 2350 became let ' s say 1800 and the new 2350 is still better than the new 1800 . Same as before . It has just shifted to a different scale . The only difference of the rescaling could be that you may be matched with higherlower differences of skills compared to before . But this also because the uncertainty has changed . But again , if your true skill has not changed , what the Matchmaking does should not have any causal effect on your skill . You will win vs worse than you and lose vs better . It ' s the not values that determines your skill , but the opposite . This is exactly the effect MMR decay has , and solves exactly the same problem MMR decay aims to solve . It is effectively the same thing . Again , no . A decay is a function of time delta MMR . Its goal is to lower your MMR if you don ' t do anything . Currently , your MMR is constant if you don ' t play so there ' s no decay . Call the supposed side effect of the rescaling differently if you want . But please , stop speaking about decay because it ' s creating confusion .
