One or more documented starting advantages plausibly enabled this lever.

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.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.

Kafelnikov turned professional at 18 in 1992 and rose rapidly, winning three ATP titles in 1994 and reaching his first Grand Slam semifinal in 1995. At 22, he won the 1996 French Open, becoming the first Russian Grand Slam singles champion. His coach Lepeshin played a key role, believing in Kafelnikov when others did not. The post-Soviet opening of Russian tennis provided a structural opportunity. He reached world No. 1 in 1999 and won Olympic gold in 2000, all by age 26.
