Sample Size
How much evidence you have — the quiet limit behind almost every football metric claim.
Definition
Single matches and small windows are noisy. Finishing variance, red cards, and game state can dominate one-game totals. Larger samples shrink noise but still need role and opponent context.
StarkPitch emphasises process reading with stated scope (periods, open play, sample) rather than courtroom verdicts from thin evidence.
Caution
A vivid chart from one fixture is still one fixture. State the sample before strong claims.
