A structural wave is external to the person, even when their position improved access to it.
Frontier geography (1/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Tomokazu Harimoto'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 Athletes, Tomokazu Harimoto's starting-advantage total is at the 96th percentile. Separately, their built or converted leverage total is at the 92th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
