Question four · where did the leverage come from?
Henrique Mecking'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 Henrique Mecking'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, Henrique Mecking's starting-advantage total is at the 15th percentile. Separately, their built or converted leverage total is at the 12th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Mecking was a self-evident chess prodigy: taught by his mother at six, winning his state championship at 11, and the Brazilian national championship at 13, the youngest ever. His mother's introduction of chess was the key early catalyst, but no dedicated coach or elite training infrastructure is documented. He became an International Master at 15 and Brazil's first Grandmaster at 20, despite Brazil having minimal chess tradition. His career was later disrupted by myasthenia gravis at age 26.
