This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Yasser Seirawan'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, Yasser Seirawan's starting-advantage total is at the 38th percentile. Separately, their built or converted leverage total is at the 36th 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.
