Model vs Closing Market

Outcome	Model	Closing Market	Difference	Signal
Wigan	37.5%	63.0%	-25.4 pp	Market Higher
Draw	29.6%	20.0%	+9.6 pp	Model Higher
Aston Villa U21	32.9%	17.0%	+15.8 pp	Model Edge

The closing market estimates Wigan's win probability at 63.0%, compared with the model's estimate of 37.5%, a difference of 25.4 percentage points. This highlights a disagreement between the model and market consensus, without 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 (Wigan win 3–2).

Post Match Insights

What worked

Expected goals projected a high-scoring match (ΣxG 2.60) — 5 goals materialised
Both Teams To Score (Yes) matched the full-time result

What failed

Over / Under 2.5: model leaned Under 2.5; match finished Over 2.5 (5 goals)
Exact score: outside the model's top score bins

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Wigan higher (62.9% vs model 37.5%, 25.4 pp), but the model's lean was validated (Wigan win 3–2).

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

Pre-match snapshot for this fixture.

League: EFL Trophy
Fixture: Wigan vs Aston Villa U21
Kickoff: 2026-08-18 18:00:00
1X2 (model): Home 37.6% · Draw 29.6% · Away 32.9%
xG (showing): Wigan 1.35 — Aston Villa U21 1.25 (total xG ≈ 2.6)
Value headline: At least one tracked line reaches the headline EV threshold — align with the hero / Primary card if shown.
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 54.5% · No 45.5%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS Yes
BTTS (model): Yes 54.5% · No 45.5%
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.

If lines move materially, re-run generation or refresh — implied probabilities and any future EV readouts will change first.

Historical Recommendation

Historical Decision: Wait

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%).
