Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Mark Edmondson against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+1Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?

Where it was dropped
0Neither way

Father was a builder. Working-class family in Gosford, NSW. Received no financial support from Tennis Australia. Worked construction and cleaned windows to fund his tennis career. No tennis connections or family wealth.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Charlie Hollis, the legendary coach who trained Rod Laver, moved to Edmondson's hometown of Gosford when Mark was 10. Hollis coached him for six years using the same methods that produced one of tennis's all-time greats. This was a fortunate and significant mentorship match.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Dedicated mentor / coach, Elite institution pipeline, Frontier geography.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Domain proximity, Started serious reps before 20, Prior reps.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Mark Edmondson's worth or future potential.
Question four · where did the leverage come from?
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.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Mark Edmondson'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.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Father had a construction company in Gosford and died of brain cancer during Edmondson's early career; Edmondson worked at his father's construction company and cleaned windows at a hospital to fund his tennis career, receiving no financial support from Tennis Australia.
No family background in tennis; father ran a construction company and Edmondson worked there to save money for his tennis travels; the family was working-class to lower-middle-class.
Edmondson grew up in Gosford, NSW, where he was fortunate that Charlie Hollis, the coach who trained Rod Laver, moved to his hometown when Edmondson was 10. Hollis coached him for six years, making Edmondson a disciple of the same methods that produced one of tennis's all-time greats. Despite being the No. 3 junior in Australia, Edmondson received no financial support and worked construction and as a hospital janitor to fund his career. His father's death from brain cancer added financial hardship. At 21, ranked No. 212, he won the Australian Open in one of tennis's greatest upsets.
