01 · Confirm the match
On a fixture list, highlight “Home vs Away” before opening the extension. Detection is a suggestion, not verification.
02 · Choose the evidence
Enter all five decimal odds from the same match and bookmaker.
Odds are entered manually because website layouts and labels vary. The model fits goal rates to these prices after normalizing the margin.
Use your own pre-match estimates. These are expected goal counts, not a predicted final score or an automatic live xG feed.
Score possibilities
MODELWhat it can—and cannot—tell you
Independent Poisson estimates, not guaranteed outcomes. The highest-ranked exact score is often unlikely. No live match, red-card, injury, lineup or weather adjustments are included.
Odds mode describes assumptions consistent with the market; it is not an independent edge over that market. Fit quality is not prediction accuracy. This model has not been backtested.
Works as a manual calculator on ordinary websites. Detection may fail on protected pages, canvas-based interfaces, frames, closed shadow roots or unfamiliar layouts. No betting-site compatibility certification is claimed.
All calculations stay inside the extension. No external services, accounts, automatic betting or broad browsing permissions. Closing this popup clears its inputs.
