Where the conditions came from
Three sources, read side by side
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Miloslav Mečíř 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
What they brought
+2Tailwind
-10+1+2+3
What capability, drive, or early skill is documented in the person rather than their surroundings?
Started tennis very young, junior champion of Czechoslovakia at 16. Notably had no coach during his professional career — entirely self-directed. Natural talent recognized early, with exceptional touch and movement earning him the nickname 'Big Cat.'
Where it was dropped
What they were handed
0Neither way
-10+1+2+3
What money, family standing, network, or permission was already in place before the work began?
Born in Bojnice, Czechoslovakia. Working-class family; father was a factory worker. No tennis connections or family domain knowledge. Ordinary family background in a small Slovak town.
The shape of the track
What surrounded them
+1Tailwind
-10+1+2+3
What place, timing, institution, or peer group made the next step available?
Czechoslovak tennis development system and Slovan Bratislava club provided basic training. Junior national champion by 16, Davis Cup debut at 18. However, notably lacked a coach during his professional career, relying on self-directed practice — limiting the ecosystem advantage.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. 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.

Perseverance and luck stay visible—not scored.
Documented perseveranceHe benefited from the Czechoslovak tennis development system and the Slovan Bratislava club, but notably had no coach during his professional career, relying on self-directed practice and natural talent.
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
Luck and unobserved varianceNo discrete luck event is documented in the reviewed biographical summaries.

Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Miloslav Mečíř's worth or future potential.
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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Miloslav Mečíř'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, Miloslav Mečíř's starting-advantage total is at the 2th percentile. Separately, their built or converted leverage total is at the 6th percentile. Other T2 profiles average 7.8 / 24 starting advantage and 12.4 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
