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 Ryu Seung-min'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 Ryu Seung-min'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 Seoul, South Korea; father ran a fast food restaurant and had health problems; maternal uncle ran a table tennis hall where Ryu first played. Parents gave up their restaurant to support his table tennis career and moved for training access.
No direct table tennis family background, but maternal uncle operated a table tennis hall and recognized Ryu's talent, providing early access to the sport. Parents made significant sacrifices, including relocating and changing careers, to support his training.
Ryu grew up in a modest family in Seoul and Incheon; his father quit his job due to health problems and ran a fast food restaurant. Ryu discovered table tennis at his uncle's hall at age 7-8 and showed immediate talent. His parents made significant sacrifices — giving up their restaurant and relocating — to support his training. He transferred schools multiple times to access better table tennis programs. By his teens, he was winning national and Asian junior championships. The Korean national team system and Samsung Life club provided elite-level training and competition infrastructure. His Olympic gold at 22 was the culmination of 15 years of intensive, specialized practice.
