Model vs Closing Market

Strong Disagreement

The closing market prices Caernarfon Town higher than the statistical model.

Largest probability gap: Caernarfon Town -35.8 pp

Outcome Model Closing Market Difference Signal
Trefelin 32.9% 10.6% +22.3 pp Model Edge
Draw 29.6% 16.1% +13.5 pp Model Edge
Caernarfon Town 37.5% 73.3% -35.8 pp Market Higher

The closing market estimates Caernarfon Town's win probability at 73.3%, compared with the model's estimate of 37.5%, a difference of 35.8 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 (Caernarfon Town win 0–2).

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Caernarfon Town higher (73.3% vs model 37.5%, 35.8 pp), but the model's lean was validated (Caernarfon Town 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.

Predictions are for informational purposes only. Always gamble responsibly and within your limits. Past performance does not guarantee future results.

AI match briefing

AI Match Summary

Model favours Caernarfon Town; market prices Caernarfon Town instead — inputs may be missing or stale.

  • Model: Trefelin 1.25 xG vs Caernarfon Town 1.35 → Caernarfon Town 37.5%
  • Market: Caernarfon Town ~73.3% implied
  • Validation failed — do not treat 1X2 EV as actionable.

Do not act on 1X2 value until validation passes. Structural leans (O/U, BTTS) need separate odds review.

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

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%).
