Does RIOT average MMR in their matchmaking system?

Title.

Obviously, this creates an issue when two teams are matched where one team's average is pulled up by one member while members of the other team are all within a small range of the team's average. I.e. the first team is almost guaranteed to have at least two losing lanes.

I haven't done much research on this so if anyone knows of an official statement from Riot that this is not their practice, I would be more than satisfied. I don't want to get into any personal anecdotes here, although I suspect that Riot does pull this shit to shorten queue times during edge cases (i.e. low popularity times, unbalanced premades, etc.).

Pretty fucking frustrating.

While you’re in queue, League’s matchmaking system puts together a game that tries to balance three things: Fair matches - Each team is roughly the same skill Position preference - You get to play a position you want to play Fast queue times - The time spent queuing is as short as possible Trying to keep these things balanced requires a lot of tuning, but here’s a rough guide on how it works behind the scenes.

To the matchmaker, a “fair” match can be loosely defined as a match in which each team has a 50% +/-1% chance of winning. In a perfect match, ten individuals with identical MMRs queue at the same time, each having selected a unique position that they’re well-suited for. That situation is incredibly rare depending on who is queueing at the time, so sometimes teams can have very slight skill differences (on average, no more than 4-5 MMR).
