Sample Size
How much evidence you have, and the quiet limit behind most metric claims.
Definition
Single matches and small windows are noisy. Finishing variance, red cards, and game state can dominate one-game totals. Larger samples reduce noise. They still need role and opponent context.
StarkPitch favours process reading with stated scope. Name the periods, phase, and sample. Avoid courtroom verdicts from thin evidence.
Caution
A vivid chart from one fixture is still one fixture. State the sample before making strong claims.
