Question four · where did the leverage come from?
Chris O'Neil's leverage provenance
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

No current annotation distinguishes self-built, enabled, or earned origins for this lever.
No decisive linked signal
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Chris O'Neil'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, Chris O'Neil's starting-advantage total is at the 6th percentile. Separately, their built or converted leverage total is at the 6th 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.

Evidence summary
Chris O'Neil won the Australian Open junior title at 17 and turned professional the same year, indicating early specialization in tennis. By 22, she won the 1978 Australian Open singles title as an unseeded player, the last Australian woman to do so for 44 years. No family background or coaching details are documented in reviewed sources. Her career was otherwise modest (19-52 record, one title), suggesting the Grand Slam win was a peak rather than a sustained trajectory.
