The betting picturemarket vs our model, market by market

“Market” = what bookmaker prices imply after removing their margin — the world's best guess. “Model” = our simulation. 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.
