In Black Ops 6, Ranked Play has greatly changed it added finer details to the Skill Rating (SR) and matchmaking system. Activision white paper published recently gives detailed information on what goes into SR's calculation, the influence of hidden MMR in matchmaking aggregator, and the tier system for rank distribution. The aim of this guide is to clarify the aforementioned concepts so that you feel at home in the competitve climate of Black Ops 6.

• Does Rank = Skill?  
• Why Do Some High-Skill Players Stay in Lower Ranks?
• Why Are Low-Skill Players Found in Higher Ranks?  
• How SR Affects Matchmaking?

↖ SR Distribution and Player Rankings  

Activision has provided detailed insights into the percentage of players in each rank. 

Key Takeaways:

• The Gold rank is populated the most widely and Gold 2 is the average skill level of the players.  
• Platinum or higher ranks are higher skill levels but progressively become a smaller percentage of the players.  
• Iridescent is extremely hard to achieve being in the top 0.5% of all players.

↖ SR and Hidden MMR Defined  

Rise in Skill Rating (SR) acts as the foundation to determine your ranking in the game Black Ops 6. Behind its scenes though, there does exists a crucial preference which is the hidden Matchmaking Rating (MMR).  

How SR functions:  

• High scores or low scores will result in either an increasing or a decreasing SR.  
• Activities carried out during the game such as making kills or working on objectives may affect the amount of SR earned or lost.  

Hidden MMR:  

• Over time, there is an invisible barometer that gauges your true talent level, and this is the MMR.  
• With invisibility ratings what you cannot see, this concept guarantees balance since it places players of equal power alongside you even when the rating displayed differs.

Mechanics of Matchmaking  

Usually matchmaking in Black Ops 6 considers both SR and hidden MMR in an effort to create fair matches.  Influencing factors:  

• SR Bracket: Players are placed in brackets with other players of a similar skill SR range to promote competitive integrity.  
• Hidden MMR: Ensures that all matches are reasonably fair, even if some players have a better visible SR than other players.  
• Team Composition: Balances sides based on skill rating to give equal chances to both the teams.

Impact of Solo vs. Party Play  

Whether you queue solo or as part of a party significantly impacts your matchmaking experience:  

Raw Skill Influence on Matchmaking  

The outcome of the matchmaking process is directly correlated to the skill level of the players represented with a hidden skill level which is at the core of the system:  

• High MMR Players: Can be matched with much higher ranking players regardless of their visible SR being lower than their skill. 
• Low MMR Players: Compete against weaker players ensuring every participant has a good experience.

↖ Does Rank = Skill?  

The simple answer is: not necessarily... It is true that rank can be influenced by skill, but other variables such as duration of play and the variability in the matchmaking system affects the player’s rank too.  

Skill Distribution Across Ranks  

• Players tend to be classified into different skill brackets according to their performance, what percentage they are from the average performance, bottom 10% for example.  
• Higher ranks like Diamond or Crimson have the highest concentration of top level skilled players that comprise around the 10% bracket.  
• Contrary to that a large percentage of gold and platinum players have a high amount of skill, but because of the limited time they might play, they remain in lower ranks.  

Skill Distribution Across Ranks  

• A few in the lower skill tier (those that made the bottom 10%) are able to earn ranks up to Silver and Gold but it is quite rare.  
• These low skilled players rather floor their rank while grinding against higher skilled players.  

Playtime as a Factor

• Skilled players who do not play the game for extensive periods might stay in the gold or platinum mid-tier brackets.  
• On the other hand, a less skilled player who extensively invests their time into playing the game will rank up higher.

Kill vs. Rank Distribution

↖ Why Do Some High-Skill Players Stay in Lower Ranks?

• Limited Active Time: Users may be able to devote only a little amount of time to Ranked Play, which can affect the rank they obtain.  
• MMR Fluctuations: Bad teammates or unfavorable MMR games may have an effect in doing so.  
• Minimum Division Placement Quota: Also, players may need to play a certain amount of matches before being placed into higher divisions.

↖ Why Are Low-Skill Players Found in Higher Ranks?  

• Grinding: Over the long run, extensive play might result in a small improvement in rank, even when no noticeable improvement in skill is observed.  
• Match Outcomes: Competitive, team-oriented victories of a single game could allow unskilled players to attain greater overall rankings.

↖ How SR Affects Matchmaking?

Skill Rating (SR) plays a central role in determining the players you are matched with in Ranked Play. 

↖ How Solo/Party  Queueing Affects Matchmaking?

Solo queueing and playing in a party significantly impact the difficulty of your lobbies. Here’s how:  

Solo Queueing:  

• Gamers will frequently battle with challengers of the same or adjacent tiers with a 1 tier difference.  
• A Bronze player in solo rank will mostly be matched up with other players of the same rank and occasionally with low tier silver players.  

Party Queueing:  

• The matchmaking system ensures the partied players face off against harder lobbies.  
• With a bronze tier rank there is a good chance of making it into a Silver, Gold or even Platinum game when in a party.

How Does SR Work?  

Skill Rating is a score given to an individual in a Ranked Play context, which signals a player's rank, and skill level progression in the game. There are two primary functions:   

• Skill Representation: Provides a clear means of viewing a user's skill.  
• Progression System: Gives players a sense of enhancement so that they are motivated to play more.

↖ Why SR is not only based on SB?

SR would not only be a pen flat metric because otherwise most players because of most player skill doesn’t change that much in a single season which tends to be within 8 weeks. Rather, there are progression mechanics built into the system to ensure that players stay engaged.

• Minimal Raw Skill Improvement: Most players don't drastically improve in skill during a single season.
• Encouraging Player Retention: A progression-based system keeps players motivated to return and improve.

Key Elements of SR Calculation  

Progression Mechanics  

• Early Gains: Players earn more SR for wins when they are far from their Target SR to accelerate early progression.  
• Reduced Gains Near Target SR: As players approach their Target SR, the amount of SR gained per win decreases to maintain a steady sense of accomplishment.  

Balancing Win Rates and SR Inflation  

• Players with Current SR significantly above their Target SR will see reduced SR gains for wins and larger deductions for losses.  
• This prevents inflation and ensures that ranks reflect both skill and sustained performance over time.

Consistency Matters  

To have an accurate reflection of your skill level, consistent play is essential:  

• Players who participate regularly in Ranked Play will see their Current SR stabilize around their Target SR over time.  
• Occasional play may result in mismatches between visible rank and actual skill.

↖ The Role Of Raw Skill On Matchmaking  

Hidden MMR, or simply raw skill, is a metric that aims to measure a player's actual capacity based on their performance. Competition Rating, which is what allows people to see what rank they currently have, differs from SR; while raw skill is more of an invisible catalyst in regards to matchmaking. What this means is, a player who uses this rank will still have to be seated against players of an equal raw skill rating no matter what the current rank might be.  

Is It The Same For All Tiers?  

In accordance with the Players Performance, the matchmaking system in Black Ops 6 adjusts and changes its setup. Given below are the different tiers and how the matchmaking differs in each.

Thr Ranked Matches system in Black Ops 6 integrates the Open Skills Rating with a concealed raw skill to make the experience more competitive. This strategy guarantees that the open skill ratings become a rewarding sense of pride while maintaining players enjoyment through a ranked progression system.

It's one step towards higher skill ranking and dedication. A system such as this was bound to happen in Call of Duty: the real gold standard.
