The betting picturemarket vs our model, market by market
“Market” = what bookmaker prices imply after removing their margin — the world's best guess. “Model” = what our machine-learning model said BEFORE this game, replayed honestly (it never saw the result). A bet is only interesting when the model sees something meaningfully more likely than the market does (the edge) — it's never about picking the winner.
