Where the conditions came from
Three sources, read side by side

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.

Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Flash (Lee Young-ho)'s worth or future potential.
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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Flash (Lee Young-ho)'s outcome attributable to any origin.
Luck is not a leftover score.
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.
Within Creators / artists, Flash (Lee Young-ho)'s starting-advantage total is at the 95th percentile. Separately, their built or converted leverage total is at the 90th percentile. Other T1 profiles average 8.7 / 24 starting advantage and 13.6 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
