This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Guðmundur Guðmundsson'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, Guðmundur Guðmundsson's starting-advantage total is at the 15th 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.
