Model vs Closing Market

Strong Disagreement

The model rates Union Magdalena considerably stronger than the closing betting market.

Largest probability gap: Union Magdalena +15.5 pp

Outcome Model Closing Market Difference Signal
Patriotas 31.0% 46.4% -15.4 pp Market Higher
Draw 29.5% 29.6% -0.1 pp Aligned
Union Magdalena 39.5% 24.0% +15.5 pp Model Edge

The statistical model estimates Union Magdalena's win probability at 39.5%, compared with the closing market's implied probability of 24.0%, a difference of 15.5 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 (Union Magdalena win 1–2).

Market Assessment

The statistical fair estimate is materially higher than the market on Union Magdalena.

  • The model may see a slower-scoring or closer matchup than the market.
  • Monitor line movement before kickoff — not a betting recommendation.

Post Match Insights

What worked

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Union Magdalena more conservatively (24.0% vs model 39.5%, 15.5 pp), but the model's lean was validated (Union Magdalena win 1–2).

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.

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%).
