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

What they brought
+2Tailwind
-10+1+2+3
What capability, drive, or early skill is documented in the person rather than their surroundings?
Harvard BA Applied Mathematics (CS). Division 1 football player and 2019 MVP. CoSIDA Academic All-America second-team. FCS ADA Academic All-Star Team. Campbell Trophy semifinalist. Built Fulltrack AI to 4M downloads and #1 sports app in India. Holds 3 patents. Exceptional combination of academic and athletic achievement.

What money, family standing, network, or permission was already in place before the work began?
From Stephens City, VA. Attended Sherando High School (regular public school). Denied US healthcare coverage and spent years navigating international healthcare — suggesting some adversity. No evidence of family wealth or domain inheritance.

What place, timing, institution, or peer group made the next step available?
Harvard University with elite academic and athletic network. Met co-founder Vivek on Harvard Cricket Club. Fulltrack AI reaching 4M downloads and #1 sports app in India. 3 patent filings. YC W25 with Vocality Health. Harvard name and network opened doors.
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
Perseverance and luck stay visible—not scored.
Documented perseveranceNot documented in the reviewed biographical summaries.
Silence in a biography is not evidence that perseverance was absent.
Encounter luckMet co-founder Vivek on Harvard Cricket Club.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Describes the starting position, not what the person later made of it.

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.

04 Observed career standing
T3 · Domain-recognized
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Brogan McPartland'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.
Complementary team1/2
Advantage-enabledmedium confidence
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.

Concentration intensity1/3
Unresolvedlow confidence
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 Brogan McPartland'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 Founders / operators, Brogan McPartland's starting-advantage total is at the 64th percentile. Separately, their built or converted leverage total is at the 68th percentile. Other T3 profiles average 5.3 / 24 starting advantage and 11.0 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
