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 Roberto Mancini against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.

What capability, drive, or early skill is documented in the person rather than their surroundings?
Described as an 'enfant prodige' — debuted in Serie A at 16, played all 30 league games, scored 9 goals. Nearly joined AC Milan at 13 (letter sent to wrong club). Exceptional early talent recognized by Bologna.

What money, family standing, network, or permission was already in place before the work began?
Father Aldo was supportive and recognized his talent, organizing the Bologna trial, but was not in the football domain. Modest rural Marche family. Father gave tactical advice ('play more backward so they notice you').

What place, timing, institution, or peer group made the next step available?
Bologna youth academy at 13, Serie A debut at 16 under Tarcisio Burgnich. Transferred to Sampdoria for £2.2 million at 17. Famous strike partnership with Gianluca Vialli. Italian football system, one of the world's strongest leagues.
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.

Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Roberto Mancini'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 Roberto Mancini'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, Roberto Mancini's starting-advantage total is at the 34th percentile. Separately, their built or converted leverage total is at the 20th 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.
