About these numbers

Scores and goals from openfootball (public domain), the newest also from OpenLigaDB (Open Database License). Neither has no shots, so there is no expected goals for this match and no finishing luck: the replay, the in-game win probability and the luck index are our own models, built from the season’s goals alone (methodology and validation). The luck index is how far the result was from what the goals say. Köln win 40% of replays (a draw counted as half).
