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 Park Joo-bong 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
+3Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Started badminton at 11, selected for South Korean national team at 16. Achieved 103 consecutive wins in men's singles between 1981-1984. World Championship silver at 18. Trajectory-changing early ability — youngest national team member as a high school freshman.
Where it was dropped
+1Tailwind
What money, family standing, network, or permission was already in place before the work began?
Father Park Myung-soo was an elementary school teacher and later principal in Imsil, a rural county. Modest family environment. Father encouraged him to pick up badminton. No significant wealth or domain connections.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
South Korean national badminton team system provided elite coaching and competitive exposure from age 16. Strong doubles partnerships (Kim Moon-soo, others). Korean sporting system emphasized rigorous training. National team selection at 16 was exceptionally early.
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, Exceptional peer / cofounder, Direct domain exposure.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Domain proximity, Started serious reps before 20.

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 Park Joo-bong'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 Park Joo-bong'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 Imsil, North Jeolla Province, South Korea; father Park Myung-soo encouraged him to start playing badminton at age 11.
Father actively encouraged his badminton career, introducing him to the sport at age 11.
