Official Rankings per Nation

Each preset captures a federation's ranking reality as a static configuration that can be provisioned to a live RankingConfig document with one click. France's preset describes Classement national + ligues + comités with a 24-month validity window and linear decay. Sweden's preset describes the SM ranking with a 12-month window and no decay, plus a national ELO.

Germany's preset describes the DPV-Rangliste with a 36-month window using weighted_years 3/2/1 (current year × 3 + previous × 2 + two years ago × 1) and the A/B/C/D tournament-category multipliers (4/3/2/1). FIPJP and CEP presets are cross-tenant — they aggregate eligible results from every participating federation into world and continental ranking lists. Per-tenant ranking formula configuration is fully exposed: each federation defines its own point model (placement × participants × level coefficient), bonus rules (e.g., Sweden bonus for beating top-10 opponent), point caps (max per competition), and thresholds (minimum match count to be ranked).

Cross-tenant ELO for casual matches runs as a global singleton config with a margin modifier — the same formula governs all casual play worldwide so cross-border casual games are first-class for ELO. Ranking history and trends compute direction (rising/falling/stable), moving averages over configurable windows, and velocity (points per month), surfaced as charts on player profiles. Ranking snapshots at qualification deadlines lock the standings as a frozen freeze — used by the national team selection committee and qualification pathway so retroactive results cannot disturb who qualified.

Disputes follow a formal process: a player files a dispute against specific points, a federation reviewer reads the case, requests evidence if needed, resolves with a decision, and the change (if any) propagates to the live ranking with audit log.
