Data Sources

Wing 11 runs on real, open-source football data. Competitions, editions, clubs, national teams, and player rosters are sourced and cross-checked from three open datasets, then committed to the repository as a canonical dataset so anyone can audit the inputs.

How ratings are computed

Player ratings are deterministic and hybrid. A campaign-derived component combines minutes played, goals, assists, clean sheets and the team’s knockout result. A small editorial-peak component reflects historical strength for players who are clearly canonical at their position. The two are blended and normalized to a 40–99 scale with position-aware floors and ceilings, then frozen per edition so identical campaigns always produce the same ratings. The methodology is open and runs in packages/data-pipeline.

Corrections

If a player, club or campaign detail is wrong, open an issue on the project repository or edit the canonical CSV. The pipeline re-validates squads (draftability, position coverage, rating ranges) on every regeneration.
