Model vs Closing Market

Strong Disagreement

The closing market prices PSG U19 higher than the statistical model.

Largest probability gap: PSG U19 -37.6 pp

Outcome Model Closing Market Difference Signal
PSG U19 45.3% 82.9% -37.6 pp Market Higher
Draw 28.9% 10.6% +18.3 pp Model Edge
Slovan Bratislava U19 25.8% 6.4% +19.4 pp Model Edge

The closing market estimates PSG U19's win probability at 82.9%, compared with the model's estimate of 45.3%, a difference of 37.6 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 (PSG U19 win 6–1).

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

Model favours PSG U19; market prices PSG U19 instead — inputs may be missing or stale.

  • Model: PSG U19 1.51 xG vs Slovan Bratislava U19 1.09 → PSG U19 45.3%
  • Market: PSG U19 ~82.9% 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 No (Yes 53.3% · No 46.7%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS No

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%).
