RR, the hidden MMR underneath it, what the act reset really does, why Riot's party rules put a ceiling on duo orders, and the three habits that decide whether the new rank sticks.
This is a roadmap for a Valorant player anywhere between Iron and Immortal who is considering a boost and wants to know what it will fix and what it will not. It covers the two numbers behind your rank, what the act reset actually does to them, why party restrictions put a ceiling on duo orders, and the habits that decide whether the new rank survives the month after the boost.
RR is the score, MMR is the judge
Your visible rank moves in Rated Rating, the bar that fills under your tier and empties when you lose. Underneath it sits a hidden MMR, Riot's private estimate of how strong you actually are. RR is what you see, MMR is what decides how much a win is worth.
When your hidden rating sits well above your displayed rank, wins pay generously and losses barely sting, which is the state every climb wants to be in. When the two agree, the gains flatten and you need a real win rate to move. This is why a player who grinds hundreds of games at the same level can feel stuck while somebody else crosses two tiers in a weekend, and it is the single most useful thing to understand before you buy anything.
Performance matters less the higher you go
At the lower and middle tiers, how you played inside the match contributes to the rating change alongside the result. Near the top of the ladder that contribution falls away and only the result counts, because at that level the system trusts wins more than it trusts a combat score. The practical reading is that a hard individual carry moves the needle in Silver through Diamond and stops doing so above it, which is also why high-tier orders take longer per tier than low-tier ones.
The act reset and what your profile remembers
At the start of every act your displayed rank is knocked down and you play a short placement run before it is shown again. Between seasons the reset is larger. In both cases your hidden rating is not deleted, it is nudged toward the middle, which is why players routinely climb back to roughly where they were and then stop dead at the same wall as last act.
Separately, your profile keeps an act rank badge built from your strongest wins of that act. It is the thing your friends actually look at, and it does not follow your current rank downward, so a short concentrated run of good games early in an act shows on the badge for the rest of it. If the badge is what you care about, say so in the order notes, because it changes how we sequence the games.
Placements are a re-measurement, not a fresh start
Because the hidden rating survives the reset, placements do not build your rank from zero. They measure how much of the gap between your knocked-down display and your surviving hidden rating gets closed immediately. The system is least certain about you right after a reset, so it moves your rating in bigger steps during that window and in smaller ones once it has a sample. A lost placement therefore costs more than a loss forty games later, and a won one pays more.
A brand-new competitive account is a different case. Once the account clears the level requirement Riot puts on the ranked queue, it plays a longer placement run with no history behind it at all, and that run has an outsized effect on everything the account does afterwards.
Booster tip: do not open an act with your first three games of the week. Warm up somewhere that does not count, then place. The placement window is the worst possible time to be rediscovering your crosshair.
Party restrictions, and why duo has a ceiling
Riot limits how far apart two players in a party can be ranked, and the window narrows as you climb. In the middle of the ladder it is wide enough that a booster a couple of tiers above you can queue with you comfortably. Near the top it shrinks until only a neighbouring division qualifies, and at the very top it is tight enough that most pairings are simply not allowed. The one exception is a full five-stack, which is permitted a wider spread and takes a rating adjustment in exchange.
This is the real reason high-tier duo orders are rarer than customers expect. It is not a policy of ours, it is the party screen refusing the queue. If your target sits above Ascendant, expect the conversation to be about a solo order, and check the current window in the client before you plan around a duo. Below that, duo is usually available and is the version of the order where you learn something.
Agent pool, role and what the account should look like
A boosted account that suddenly plays four agents it has never touched leaves an obvious trail in its own match history, and more importantly it leaves you with a rank you cannot hold on agents you do not play. Tell us the constraints up front.
The agents you actually own and want played.
Any agent you refuse to see on your match history.
The role the account should look like it plays, whether that is duelist, controller, initiator or sentinel.
Whether you want the pool kept deliberately narrow so the profile stays consistent.
Our default without instructions is a narrow pool on the role your recent history already shows, which is both the safest for the account and the closest to the rank you will have to defend afterwards.
Comms discipline
On a duo order there is one rule that matters more than the rest, which is that one person calls. Usually that is the booster, because they are reading the round faster. Two people calling different rotations loses more rounds than a missed shot ever will. Mute a teammate who is arguing rather than answering them, and keep the information factual, meaning positions, timers and utility rather than opinions about the last round.
On a solo order the booster does not type or speak on your account at all. That costs a little in coordination and it is worth it, because an account that never talks is an account that never gives anyone a reason to look at it.
Keeping the rank after the boost
A rank you cannot hold is a rank you rent. Three habits do most of the work of turning a boosted tier into your own.
Review two rounds, not two games. Pick the round you died first in and the round you lost the site on, watch them back at half speed, and answer one question each time, which is what information you had at the moment you committed. Two rounds a day beats an hour of passive VOD watching.
Warm up, then cap your session. One deathmatch or range routine before the first ranked game, and a hard stop after two consecutive losses. Tilt does not make you play badly in a dramatic way, it makes you play slightly worse for six straight games.
Shrink the pool. Two agents you are genuinely good at, plus one specialist for the map you keep losing on. Depth is a top-tier luxury and a middle-tier trap.
If you want the review habit built into the order itself, ask for it in chat before the first match. Boosters can leave notes on the order page about what they changed and why, and reading those against your own recording is the fastest coaching you will get for free.
