This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Martina Navratilova'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, Martina Navratilova's starting-advantage total is at the 99th percentile. Separately, their built or converted leverage total is at the 92th 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
Navratilova was born into a family with deep tennis roots: her grandmother was a nationally ranked Czechoslovak player, her mother was a multi-sport athlete, and her stepfather became her first tennis coach. She started playing at age 4, won the Czechoslovak national championship at 15, and her first professional title at 17. After defecting from communist Czechoslovakia at 18 in 1975, she reached two Grand Slam singles finals that same year. By 21, she won Wimbledon and became world No. 1. The combination of family tennis lineage, early intensive training, and the urgency of defection catalyzed her extraordinary career.
