Model vs Closing Market

Strong Disagreement

The model rates Yokohama F. Marinos considerably stronger than the closing betting market.

Largest probability gap: Yokohama F. Marinos +22.2 pp

Outcome Model Closing Market Difference Signal
Shimizu S-pulse 20.4% 38.3% -17.9 pp Market Higher
Draw 24.7% 29.1% -4.4 pp Aligned
Yokohama F. Marinos 54.9% 32.7% +22.2 pp Model Edge

The statistical model estimates Yokohama F. Marinos's win probability at 54.9%, compared with the closing market's implied probability of 32.7%, a difference of 22.2 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 (Yokohama F. Marinos win 0–1).

Post Match Insights

What worked

  • Yokohama F. Marinos attacking xG significantly stronger (1.93 vs 1.12)
  • Exact score 0–1 fell within the model's highlighted bins

What failed

  • Both Teams To Score: model leaned BTTS Yes; match finished BTTS No
  • Over / Under 2.5: model leaned Over 2.5; match finished Under 2.5 (1 goals)

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Yokohama F. Marinos more conservatively (32.7% vs model 54.9%, 22.2 pp), but the model's lean was validated (Yokohama F. Marinos win 0–1).

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.

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%).
