Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Vitor Belfort against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Started boxing at 12, won Brazilian National Jiu-Jitsu Championships (absolute and heavyweight) at 17, and won UFC 12 at 19. 'The Phenom' — exceptional early combat sports ability with rapid progression across disciplines.
Where it was dropped

A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Elite institution pipeline, Dedicated mentor / coach, Frontier geography.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Domain proximity, Started serious reps before 20, Prior reps.
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 Vitor Belfort'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 Vitor Belfort'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."
Born and raised in Rio de Janeiro, Brazil; family details not extensively documented. Moved to the US at 19 with his mother and sister to compete.
No documented family background in martial arts or combat sports.
