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 Stefka Kostadinova 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?
Attended a specialist sports school in Plovdiv, introduced to high jump at 12-13, jumped 166cm in 6th grade and 190cm by 10th grade. Set a world record of 2.09m at 22 that stood for 37 years. Exceptional athletic talent.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Parents divorced when she was 4; raised by her mother with help from grandparents on a single salary and pensions. Modest family with no athletic background or wealth.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Specialist sports school in Plovdiv, Bulgarian state athletics system, and coach Nikolay Petrov (who became her husband) provided sustained elite-level training. The Bulgarian athletics pipeline was among the world's best for high jump.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. 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, Prodigy / innate ability, 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.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Stefka Kostadinova'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 Stefka Kostadinova'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 in Plovdiv, Bulgaria. Attended a specialist sports school. No specific family financial or domain background documented in reviewed sources.
