J3 League · Sunday, 16 August 2026 · 10:00. Final score 4–2 (half-time 1–1). Before kick-off we rated it 56% under 2.5 goals — the match finished with 6, so that call missed. 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 | 2.20 | 43% | 45% | +2% |
| Under 2.5 goals | 1.65 | 57% | 55% | -2% |
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: Osaka 1.65, draw 3.40, Parceiro Nagano 4.50.
The league sets the starting point. J3 League has produced over 2.5 goals in 47% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Osaka have 0 in 1 this season, Parceiro Nagano 0 in 1. 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 45% and 45%.
Last season still counts, briefly. With 1 and 1 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 45% and 40%.
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 43%.
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 43%.
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 48%, from expected goals of 1.48 for Osaka and 1.12 for Parceiro Nagano. Folding in 30% of that view gives 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.
