How OpenRating Works

The OpenRating system is tuned for multi-level badminton competitions and built to extend across sports. Here is the snapshot view; a full whitepaper and API documentation will follow.

Transparent ratings

OpenRating applies probabilistic skill estimation tuned for badminton match formats. Each update publishes volatility and confidence intervals so stakeholders understand certainty levels.

Data pipeline

Results ingest from sanctioned BWF events, normalized through our schema, and fed into nightly rating updates. Pending matches queue for review to prevent stale ladders.

API-first access

The public REST API exposes ladders, player snapshots, and match history. Rate limiting ensures partner apps and the public site can coexist without contention.
