FEN Scoring & Rankings
On FEN, Scrims are not just training matches. They are structured competition where every completed Scrim contributes to Roster rankings, Player rankings and competitive history.
FEN Competition
Scrims on FEN are competition
Scrims are often used as training in competitive gaming. FEN keeps the familiar Scrim format but gives it a competitive purpose.
Every Scrim counts.
A FEN Scrim contains three competitive matches across different modes. Each match result is recorded, the overall Scrim winner is determined, and the performance becomes part of the FEN ranking system.
The important difference: FEN does not simply add raw Call of Duty match scores together. Scrim results and individual Player performances are converted into separate competitive rankings.
Core Principle
Two rankings. Two different purposes.
FEN does not treat a Roster and an individual Player as the same thing. Team performance and personal performance are calculated separately.
Roster Ranking
The Roster ranking represents how the team performs together. It uses an Elo-based system and changes according to the final result of a completed Scrim.
Player Ranking
The Player ranking represents the individual’s own competitive performance. It belongs to the Player profile and remains independent from whichever Roster the Player currently represents.
Roster performance belongs to the Roster. Personal performance belongs to the Player.
Scoring Flow
How a FEN Scrim is scored
A Scrim contains three matches. Each match result is recorded, but the Roster Elo is updated once for the completed Scrim.
1. Play the three matches
The Scrim is played across three competitive matches, such as Hardpoint, Search & Destroy and Domination.
2. Determine the winner
Match wins determine the overall Scrim result. A Roster can therefore win the Scrim 2–1 or 3–0.
3. Update the rankings
The Roster Elo is updated once from the final Scrim result. Player performances are calculated from the individual matches they actually played.
One Scrim = one Roster Elo event. The three individual matches do not create three separate Roster Elo increases or decreases.
Team Performance
How the Roster ranking works
Roster ranking measures the competitive strength of the team, rather than the amount of raw in-game points accumulated.
Starting Elo
A Roster begins with a base Elo rating of 1000. The rating then moves up or down according to competitive results.
Elo-based calculation
FEN compares the rating of both Rosters before the Scrim. Winning against a stronger opponent can therefore be more valuable than beating a lower-rated opponent.
One update per Scrim
The final Scrim result determines the Roster Elo adjustment. Raw scores from the three matches remain match statistics.
Simple Elo example
Imagine two equally rated Rosters both begin the Scrim at 1000 Elo.
With FEN’s current K-factor of 32, the winner moves approximately to 1016 and the losing Roster moves approximately to 984.
Winning Roster
Losing Roster
A Hardpoint score of 250 does not mean the Roster gains 250 ranking points. Raw match scores and Roster Elo are two different things.
Individual Performance
How the Player ranking works
Individual Players need a different scoring system because personal performance cannot be represented properly by the Roster win or loss alone.
Match by match
Player performance is calculated from the competitive matches the Player actually participates in.
Normalised 0–100 score
Match performance is converted to a 0–100 score rather than simply adding raw Call of Duty points together.
Long-term ranking
The Player leaderboard uses the average of valid match performance results, creating a ranking that develops over time.
Player performance weighting
FEN currently combines three parts of individual match performance.
50%
Normalised in-game score.
30%
Player impact.
20%
KDA performance.
A Player with a raw match score of 250 does not receive 250 leaderboard points. The performance is normalised first and becomes part of the Player’s long-term 0–100 performance ranking.
Player Identity
Your Player ranking belongs to you
A Player’s personal competitive ranking is independent from the Roster they currently represent.
Change Roster without losing your ranking.
If you leave one Roster and join another, your Player ranking stays attached to your FEN Player profile.
Your personal performance history does not disappear, reset or transfer to the Roster.
Example: Player moves team
A Player competing for Roster A builds their personal ranking through FEN Scrims.
If that Player later joins Roster B, their Player ranking continues from where it was.
Roster ranking stays separate
Roster A keeps its own Elo and competitive history. Roster B keeps its own Elo and competitive history.
The Player does not bring Roster Elo from one team into another.
This is why FEN has two leaderboards. Players can build their own competitive identity while Rosters build a completely separate team record.
Worked Example
One Scrim. Two ranking systems.
The same Scrim produces both a team result and individual Player performance records.
Match 1
Roster A wins Hardpoint. Match statistics and individual Player performances are recorded.
Match 2
Roster B wins Search & Destroy. The overall Scrim is now tied 1–1.
Match 3
Roster A wins Domination. The final Scrim result is 2–1 to Roster A.
Roster result
Roster A receives the Scrim victory. The Elo system updates both Roster ratings once.
Player result
Each Player’s individual match performances are calculated separately and added to their personal ranking history.
A Player on the losing Roster can still record a strong individual performance. Team results and Player performance are intentionally not the same measurement.
Why FEN Works This Way
Teams and Players deserve separate recognition
Competitive team play depends on more than individual statistics, while individual Players also need a competitive identity that does not disappear when their team changes.
Roster success
Teamwork, communication, tactics, consistency and match results determine how successful a Roster is as a competitive unit.
Player performance
Personal performance can continue across different Rosters, allowing Players to build a long-term competitive profile on FEN.
FAQ
Frequently Asked Questions
The key things to understand about FEN Scrims, Roster Elo and Player rankings.
Are FEN Scrims just training matches?
No. FEN treats Scrims as structured competition. Results contribute to rankings, leaderboards and competitive history.
Does every match change the Roster Elo?
No. Match results determine the overall Scrim winner, but the Roster Elo is updated once for the completed Scrim.
Is a Hardpoint score of 250 worth 250 ranking points?
No. Raw in-game scores remain match statistics. They are not directly added to either the Roster Elo or the Player leaderboard.
Does the Player leaderboard use Elo?
No. Roster competition uses Elo. Player ranking uses a normalised individual performance system designed for match-by-match Player performance.
What happens if I change Roster?
Your Player ranking stays with your Player profile. Your personal competitive progress is not reset when you leave one Roster and join another.
Does my Player ranking affect my new Roster’s Elo?
No. Player rankings and Roster Elo are separate. A Roster keeps its own rating regardless of which Players join or leave.
Why does FEN separate Player and Roster rankings?
Because a team result and an individual’s performance measure different things. FEN allows both to develop independently.
Will this system also support Leagues and Tournaments?
FEN’s competitive structure is designed to grow beyond Scrims into broader organised competition, including Leagues and Tournaments as the platform develops.
