Model vs Closing Market

Outcome	Model	Closing Market	Difference	Signal
Kochi United	31.0%	37.2%	-6.2 pp	Market Higher
Draw	29.5%	30.6%	-1.1 pp	Aligned
Roasso Kumamoto	39.5%	32.1%	+7.3 pp	Model Higher

The statistical model estimates Roasso Kumamoto's win probability at 39.5%, compared with the closing market's implied probability of 32.1%, a difference of 7.3 percentage points. This highlights a substantial disagreement between the model's assessment and the market consensus, rather than indicating which view is ultimately correct.

Model probabilities are generated from the statistical xG model using a Poisson distribution. Closing market probabilities are derived from consensus closing 1X2 odds after margin removal. Values represent implied probabilities rather than betting recommendations. Closing snapshot: PRE1.

After full time, the model's directional lean matched the result (Roasso Kumamoto win 0–2).

Market Assessment

The fair estimate shows a modest edge over current market pricing on Roasso Kumamoto.

Monitor line movement before kickoff — not a betting recommendation.

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Roasso Kumamoto more conservatively (32.2% vs model 39.5%, 7.3 pp), but the model's lean was validated (Roasso Kumamoto win 0–2).

Review FAQ

How accurate was the prediction?: This page grades directional markets (1X2, Over/Under 2.5, BTTS) against the full-time result. The prediction grade reflects how many of those tracked markets matched reality.
What does xG Accuracy measure?: xG Accuracy compares the model's pre-match expected-goals profile to the actual scoreline — not whether every market hit. A strong directional review can coexist with a moderate xG accuracy score.
Why wasn't the exact score predicted?: Correct-score outcomes are low-probability tails even when the model reads the match profile well. We highlight top score bins for context; missing the exact line does not invalidate a directional review.
Does this improve the AI record?: Each finished match is logged in our validation pipeline. Aggregated hit rates and CLV studies are published separately — this page is the per-match audit trail.

AI match briefing

AI Match Summary

Below is a compact, numbers-first snapshot aligned with the same engine as the cards above.

League: J3 League
Fixture: Kochi United vs Roasso Kumamoto
Kickoff: 2026-08-30 10:00:00
1X2 (model): Home 31.0% · Draw 29.5% · Away 39.5%
xG (showing): Kochi United 1.21 — Roasso Kumamoto 1.39 (total xG ≈ 2.6)
Value headline: None — no positive EV on tracked lines at current best prices (same as the decision block: no default bet).
Structural leans (not bets): Structural lean (model): O/U 2.5 Under 2.5 (Under 2.5 51.8% · Over 2.5 48.2%); BTTS Yes (Yes 54.3% · No 45.7%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS Yes
BTTS (model): Yes 54.3% · No 45.7%
Correct score (top bin): 1-1 (12.5%)

Saying “no value” on a snapshot is a feature, not a bug: it protects readers from forcing a play when the edge is not there.

Prefer skipping to over-staking when the engine is honest about missing edge.

Historical Recommendation

Historical Decision: Monitor

Outcome: Validated — Pre-match lean validated against the full-time result.

Risk Factors Considered Before Kickoff

Price movement: implied probabilities and EV move with odds.
Sample / data gaps: low-information leagues widen forecast bands.
In-play state: goals and red cards are not modelled here.
Scoreline variance: the most likely scoreline is still usually a low absolute probability outcome (often well below 20%).
