This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Ding Ning'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.
Within Athletes, Ding Ning's starting-advantage total is at the 87th percentile. Separately, their built or converted leverage total is at the 97th percentile. Other T1 profiles average 8.9 / 24 starting advantage and 13.6 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
