Question four · where did the leverage come from?
Kim Duk-koo'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 Kim Duk-koo's outcome attributable to any origin.
Luck is not a leftover score.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, Kim Duk-koo's starting-advantage total is at the 25th percentile. Separately, their built or converted leverage total is at the 12th percentile. Other T4 profiles average 5.7 / 24 starting advantage and 10.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Kim rose from extreme poverty in rural South Korea, learning to fight on the streets before entering amateur boxing at 17. He compiled a 29-4 amateur record, turned pro at 23, and won the OPBF lightweight title at 26 to become the WBA's top contender. His trajectory was driven by adversity and physical toughness rather than any documented family advantage or institutional pipeline. His death in a world title fight against Ray Mancini prompted major boxing safety reforms.
