This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Mariana Constantin'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, Mariana Constantin's starting-advantage total is at the 65th percentile. Separately, their built or converted leverage total is at the 23th percentile. Other T3 profiles average 7.0 / 24 starting advantage and 11.7 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
