Model vs Closing Market

Moderate Disagreement

The closing market prices CSKA Sofia higher than the statistical model.

Largest probability gap: CSKA Sofia -8.1 pp

Outcome Model Closing Market Difference Signal
Spartak Varna 16.5% 15.9% +0.6 pp Aligned
Draw 30.2% 22.6% +7.5 pp Model Higher
CSKA Sofia 53.3% 61.5% -8.1 pp Market Higher

The closing market estimates CSKA Sofia's win probability at 61.5%, compared with the model's estimate of 53.3%, a difference of 8.1 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: PRE5.

After full time, the result was Draw 1–1.

Market Assessment

The market and model broadly agree on CSKA Sofia. The remaining divergence may reflect differences in team-strength assumptions rather than a directional disagreement.

  • Monitor line movement before kickoff — not a betting recommendation.

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

Pre-match snapshot for this fixture.

  • League: First League
  • Fixture: Spartak Varna vs CSKA Sofia
  • Kickoff: 2026-09-05 16:00:00
  • 1X2 (model): Home 16.4% · Draw 30.2% · Away 53.4%
  • xG (showing): Spartak Varna 0.69 — CSKA Sofia 1.43 (total xG ≈ 2.12)
  • Value headline: None (actionable) — best tracked EV is about +0.2%, still below the +2.0% minimum for a headline / default stake (no default bet).
  • Structural leans (not bets): Structural lean (model): O/U 2.5 Under 2.5 (Under 2.5 64.4% · Over 2.5 35.6%); BTTS No (Yes 39.5% · No 60.6%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS No
  • BTTS (model): Yes 39.5% · No 60.6%
  • Correct score (top bin): 0-1 (17.2%)

When book depth is thin or odds are missing, EV may be unavailable even though the model still prefers one side on totals or BTTS — wait for cleaner prices or skip.

If lines move materially, re-run generation or refresh — implied probabilities and any future EV readouts will change first.

Historical Recommendation

Historical Decision: No Primary Bet

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%).
