A draw is its own outcome: the model has a band around an even contest in which a draw is the likeliest single result, fit on the tuning seasons.
The market comparison uses the bookmakers' closing odds with their margin taken out.
Team news, injuries and rotation for European games are not in the model.
Expected goals are not in the rating yet; it learns only from results.
