| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 49% | 51% | Under |
| Over 3.5 goals | 28% | 72% | no pick |
| Both teams to score | 55% | 45% | Yes |
The result model puts Consadole Sapporo at 25%, the draw at 26% and Shonan Bellmare at 49%, from expected goals of 1.07 and 1.58.
The league sets the starting point. J2 League has produced over 2.5 goals in 46% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Consadole Sapporo have 6 in 12 this season (3 of 6 at home), Shonan Bellmare 3 in 12 (2 of 7 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 47% and 39%.
Last season still counts, briefly. With 12 and 12 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 52% and 44%.
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 48%.
Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 50%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 48%.
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 1.07 for Consadole Sapporo and 1.58 for Shonan Bellmare. Folding in 30% of that view gives 48%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 49%.
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.
| Team | Games | O2.5 | O3.5 | BTTS |
|---|---|---|---|---|
| Consadole Sapporo | 12 | 50% | 25% | 67% |
| Shonan Bellmare | 12 | 25% | 17% | 67% |
Our numbers give this match a 69% chance of at least one goal before half-time and 30% of two or more. The J2 League rates are 67% and 30%. After the break: 78% for a goal and 42% for two or more (league 76% and 40%). Consadole Sapporo's last 50 games had a first-half goal 78% of the time and a second-half goal 86%; Shonan Bellmare's last 50, 64% and 80%. Team form says less about a single half than about a full match, so these numbers stay close to the league's.
Every match ranked the same way: first half goals today · second half goals today · tomorrow.
