The Valorant developers’ team addressed the player’s base in their latest Q & A request to clarify all the intricacies concerning the ranking matchmaking. They explained in detail how it works in the background.

— VALORANT (@PlayVALORANT) March 18, 2021 It is important to note that the Ranked Rating (RRs) can be seen by players on their profiles and tracked by playing ranking matches. On the other hand, MMR is a secret metric that tracks the skills of a player. Thus, while preferably the same way RR and MMR in Valorant may differ, and in some cases, they are quite disparate. To begin with, the rank of a Valorant player needs to be repeated separately from its MMR. The players can’t ever see their MMR—this is the algorithm used by Valorant for creating fair matches. When a player queues in or after an episode reset, the Valorant matchmaking algorithm takes a guess of the ball garden where the “Rank” of a player belongs since the player’s MMR guidelines are used. Sadly, the algorithm has an “idea” only, so it puts the player at the bottom of what they think the player is. In the Q&A, Valorant devs discuss why the player is best at putting the player in the lower end of the spectrum. It’s the “Convergence” they say. As the player wins more, as they are officially combined with players below their real level of ability, they get more RR points per victory and fewer per loss. Now that the algorithm places a player in their ranks, RR gain/loss will be even for every game of win/loss. The players will probably hold a 50% win rate while the player is at their MMR. Due to the good winning route or a few nice games, the devs said again that it doesn’t change the fact that they only have a 50 percent winning rate and are now higher than their MMR. In addition to the protection of demotion, players frequently sit above their MMR. This is a problem. On the other hand, a player may be able to have a ranking higher than their MMR at the end of the day. The devs explained how their systems deal with this scenario: The devs addressed Valorant’s dilemma of “out-of-grind MMR” and how their system fixed it. They stressed that all Valorant players follow the same standards: you need to show that they are better than they were above them in order to ascend. So if you win a bit over half of your games and 200 wins, when another player wins a vast majority of your games but only has 100 wins, then a 100-wins would probably be higher on the leaderboard due to your MMR. In short, some important points are listed below:

If a player’s MMR is higher than their rank, they’ll gain more RR on wins than they lose on losses. If a player’s MMR is even with their rank, they’ll gain and lose closer amounts of RR for wins and losses. If a player’s MMR is lower than their rank, they’ll gain less RR on wins and lose more on losses.
