The Fighting Game Performance Index (FGPI)
Overview
The Fighting Game Performance Index (FGPI) is a single number that summarizes a player's overall competitive strength in Street Fighter 6. Rankings tell you who placed where. FGPI estimates how strong a player is right now by considering results along with consistency, recent form, and event context / schedule difficulty (see also T3R and Performance Floor).
FGPI vs. Rankings
| Aspect | Rankings (Results Only) | FGPI (Performance Rating) |
|---|---|---|
| Primary Signal | Final Placements in Offline Tournaments | Holistic Performance Indicators, Including Results |
| Goal | Reflect Standings Based Purely on Outcomes | Measure Overall Competitive Strength |
| Time Sensitivity | Recency via Results Cadence | Responsive to Recent Form and Trend |
| Context Awareness | Mostly Implicit from Event Scale | Explicitly Accounts for Context and Consistency |
| Usage | "Who Is Ahead on Results?" | "How Strong Are They Right Now?" |
Summary: Rankings are the scoreboard. FGPI is the scouting report. Rankings reward outcomes. FGPI estimates present strength when context and recency matter.
How FGPI Works (High Level)
FGPI blends multiple signals observed over the last 12 months. The FGPI score is informed by:
- Outcome Quality Over Time: Results matter with extra attention to major events.
- Consistency: Avoiding low finishes and establishing a reliable baseline are rewarded.
- Recent Form: The rating responds to current momentum, not only historical peaks.
- Competitive Environment: Event context and field strength are considered.
- Opponent quality and event scale: Performances against higher rated opponents and deeper fields at majors provide stronger evidence of competitive strength.
- Recency Weighting: Older results taper so that current performance matters more.
In short, FGPI aims to answer: How strong is this player right now, accounting for consistency and context, not just raw placement totals?
Guardrails and Eligibility
- In Person Events: Inputs focus on offline competition to stay aligned with our ranking system.
- Sufficient Activity: A minimum level of recent participation ensures the rating is statistically meaningful.
- Stability Checks: Internal safeguards help prevent single outliers from overly distorting a score.
Interpretation and Caveats
- Direction: Higher FGPI means stronger current form. Small week-to-week moves are normal.
- Similar Scores: Break ties with T3R, recent opponents, and consistency.
- Not a Seeding List: FGPI complements not replaces results-based seeding and rankings.
Head-to-Head Illustration
This compact, fictional dataset shows why FGPI can differ from results-only rankings. Numbers are illustrative.
| Player | Event | Scale | Field Strength* | Placement | When |
|---|---|---|---|---|---|
| A | Premier Open | Major | High (6 Top 20 Entrants) | 5th | 2 Weeks Ago |
| Championship Circuit | National | High (3 Top 20 Entrants) | 9th | 6 Weeks Ago | |
| B | City Throwdown | Regional | Low (0 Top 50 Entrants) | 1st | 3 Weeks Ago |
| Weekend Bracket | Regional | Low (0 Top 50 Entrants) | 1st | 8 Weeks Ago |
Why FGPI can rate A higher than B
- Opponent quality: A earned results against several top 20 opponents while B faced mostly unranked fields.
- Event context: Majors and nationals tend to have deeper brackets than regionals which increases evidentiary value.
- Recency and trend: A’s strong major result was very recent and moves the index more than B’s older regional win.
- Consistency floor: A’s 5th and 9th indicate a higher floor than B’s untested record versus elite fields.
- Robustness: FGPI reduces volatility from softer brackets and rewards performances that generalize against stronger opponents.

What-If Scenarios
How might these scores change under different conditions?
What if B wins a national next month?
FGPI would likely swing toward B. A larger scale event with a deeper field adds stronger signal and the recency weight is significant. Depending on A's results in the same window, B could pass A on FGPI and also on rankings.
What if A exits early at a major while B keeps winning regionals?
A's FGPI would drop due to the low finish and loss of momentum. Without tougher fields for B, the gap may narrow rather than fully invert.
When do FGPI and rankings agree most?
When top placements happen at majors or nationals against deep fields and recency aligns. In those cases both systems point to the same leaders.
FAQ
Is FGPI better than rankings?
They answer different questions. Rankings reflect results. FGPI estimates overall strength and trend. Use both for the clearest picture.
How often does FGPI update?
FGPI scores update whenever new offline results are registered.
Where do I see FGPI?
FGPI appears on the Player Stats Leaderboard and on individual Player Profiles.
What is the typical FGPI range?
Scores are on a 0 to 100 scale.
Why might a player climb without winning?
Strong finishes against deep fields or improved consistency can raise FGPI even without a first place finish.
