A soft bookmaker offers X at 2.90 — above the fair price of 2.78 implied by the sharp market. Market Gap +4.4%.
The fair price comes from the sharp market itself: we strip the margin from Pinnacle-style odds — the most accurate public predictor in existence — and use our calibrated Elo + form model as a cross-check and as the fallback where no sharp price exists. Value is flagged only where a softer bookmaker prices a selection above that fair price, never on long shots (implied probability under 30%), and never beyond a plausible band. Most of the time there is no value — and we say so.
