Model vs Closing Market

Strong Disagreement

The model rates Septemvri Sofia considerably stronger than the closing betting market.

Largest probability gap: Septemvri Sofia +32.1 pp

Outcome Model Closing Market Difference Signal
Septemvri Sofia 56.1% 24.0% +32.1 pp Model Edge
Draw 25.0% 30.5% -5.5 pp Market Higher
Arda Kardzhali 18.9% 45.5% -26.6 pp Market Higher

The statistical model estimates Septemvri Sofia's win probability at 56.1%, compared with the closing market's implied probability of 24.0%, a difference of 32.1 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 result was Draw 1–1.

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 Septemvri Sofia; market prices Arda Kardzhali instead — inputs may be missing or stale.

  • Model: Septemvri Sofia 1.89 xG vs Arda Kardzhali 1.03 → Septemvri Sofia 56.1%
  • Market: Arda Kardzhali ~24.0% 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.

Historical Recommendation

Historical Decision: Wait

Outcome: Missed — Pre-match 1X2 lean did not match 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%).
