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."
Born in Barcelona, Spain; father Luis Bruguera was a former Spanish Davis Cup player and federation coach who served as Sergi's primary tennis coach from age five. Sergi is an only child.
Father Luis Bruguera was a former Spanish Davis Cup player and leading federation coach who provided sustained, individualized tennis training throughout Sergi's early career, representing deep family-domain advantage.
Bruguera's primary early advantage was family-domain apprenticeship through his father Luis, a former Spanish Davis Cup player and federation coach who served as his coach from age five. Growing up in Barcelona during the rise of Spanish clay-court tennis provided geographic and structural advantages. No evidence of family financial advantage beyond the coaching relationship was found in reviewed sources. His rapid professional rise, ATP Newcomer of the Year at eighteen and first ATP title at twenty, reflects the combination of paternal coaching and early professional immersion.
