Inputs: current competition and team state
Use the official Serie A standings to identify the current competition state, then retain fixture, venue, lineup status, data cutoff and source timestamp. Table position and goal difference are context, not a probability forecast.
| Evidence layer | Required record |
|---|---|
| Official | Competition edition, fixture and table retrieval |
| Provider | Field definitions, coverage and corrections |
| Team | Availability, lineup state, role and schedule |
| Model | Target, version, cutoff and uncertainty |
| Product | Exact US market, price, stake and rule |
Test league stories
Do not assign an under or draw because Serie A is described as tactical. Define a measurable feature and test whether it improves later probability quality beyond a baseline. Opta's definitions show why football event metrics need a named provider.
Translate result and goals products
DraftKings' soccer rules provide one current US example of regulation-time result, total, handicap and player settlement. Preserve the local rule and full score distribution around an exact line.
A 0-0 and 1-1 both draw, but they have different total-goal, BTTS, scorer and handicap outcomes. One result probability cannot be reused across those markets.
Validation
scikit-learn's TimeSeriesSplit documentation explains chronological model evaluation. Use scikit-learn's calibration guidance to test stated probabilities on all eligible later fixtures.
Test performance by season, club-change state, result market, goal line and price band. Keep abstentions and unavailable prices in the denominator.
Dependence
Same-match result, total, BTTS and prop legs occupy the same score and player states. OpenStax's independence condition must be justified for cross-match multiplication as well, because model and provider errors can be shared.
Publication record
- Freeze official fixture and team evidence.
- Define the exact market and settlement scope.
- Produce a complete probability distribution and uncertainty range.
- Compare with the accepted price and retain failed execution.
- Map dependence across every proposed leg.
- Reconcile final settlement without changing the forecast.
Market-specific abstention rules
Under the market distinctions in DraftKings' current soccer rules and the probability checks in scikit-learn's calibration guidance, abstain from a total when the model stores only mean goals and cannot reconstruct probability around the offered line. Abstain from a player leg when role or participation states are missing. For result markets, retain home, draw and away together; a strong home estimate cannot be evaluated properly if the other outcome probabilities were discarded.
Reopen the analysis when the official fixture changes, a material lineup input arrives, the provider corrects an event field, or the accepted product uses a different period or line. The new version should reference the old one instead of silently replacing it, which preserves a fair chronological audit.

Assumptions and limitations
This page publishes no current picks or fixed league tendencies. Competition state, teams, prices, data and tactical relationships change. A historically useful feature may fail in a new season or at a different market line.
