Championship · Saturday, 15 August 2026 · 15:00. Final score 0–2 (half-time 0–1). Before kick-off we rated it 56% under 2.5 goals — the match finished with 2, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

| Market | Price | Implied | Our rating | Edge |

| Over 2.5 goals | 2.00 | 47% | 45% | -3% |

Implied percentages have the bookmaker's margin removed, so they add to 100 and can be compared with our rating directly. Edge is simply the gap between the two. A positive edge means our model thinks the outcome is likelier than the price suggests — it is not a tip, and a high probability with a negative edge is a poor bet however safe it looks. Prices are a pre-match snapshot from a single bookmaker and move constantly.
Match odds: Bristol City 2.55, draw 3.40, Millwall 2.75.
The league sets the starting point. Championship has produced over 2.5 goals in 51% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Bristol City have 0 in 0 this season, Millwall 0 in 0. Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 51% and 51%.
Last season still counts, briefly. With 0 and 0 games played this season, last season's rates are still blended in and fade out entirely by game 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 46% and 46%.
The mix. Weighted 40% home side, 40% away side and 20% league — the split that beat every alternative across 30,582 matches of testing — that gives 47%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 40%. That nudges the number 10% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 46%.
Goal expectation. Separately a Poisson model built from attack and defence strength — using real expected-goals data where the league has it — puts this match at 49%, from expected goals of 1.43 for Bristol City and 1.22 for Millwall. Folding in 30% of that view gives 47%.
Season opener. One of these sides has not played a league game yet. Openers run about 2.5 points under their league's norm, measured across 2,727 of them, so the rating is docked to 45%.
This breakdown is generated from the same inputs the rating uses, so it cannot describe a calculation we did not perform. The full model is set out in the methodology.
