Gaetano Scirea's leverage provenance
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Gaetano Scirea's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Within Athletes, Gaetano Scirea's starting-advantage total is at the 38th percentile. Separately, their built or converted leverage total is at the 97th percentile. Other T1 profiles average 8.9 / 24 starting advantage and 13.6 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
