No decisive linked signal
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Janica Kostelić'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, Janica Kostelić's starting-advantage total is at the 65th percentile. Separately, their built or converted leverage total is at the 58th 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.

Evidence summary
Kostelić's entire childhood was organized around skiing by her father Ante, who coached both her and her brother Ivica (a future World Cup champion) full-time. The family had minimal financial resources and no institutional support, sleeping in their car during training camps and fleeing war in Yugoslavia. Despite these constraints, Ante's obsessive coaching (1,200 gates per day vs. 400 for others) and the sibling rivalry with Ivica produced one of the greatest ski racers in history. She debuted in the World Cup at 16, won her first race at 17, and was overall champion at 19.
