Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Sérgio Santos's worth or future potential.
Question four · where did the leverage come from?
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.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Sérgio Santos'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.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Grew up in the periphery of São Paulo in a low-income family; worked multiple menial jobs during adolescence including as a supermarket packer, office boy, and street vendor.
Not documented in reviewed sources as having volleyball or athletic domain expertise in the family.
Santos grew up in poverty in São Paulo's periphery, working menial jobs while pursuing volleyball. He started at Palmeiras at 17 and was playing in the Superliga by 1996. The creation of the libero position in 1998 was a structural opportunity that fit his defensive skills. Brazil's dominant volleyball culture and national team pipeline provided the ecosystem for his rise. His national team debut at 25 in 2001, winning World League gold, was the qualifying milestone.
