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

+2Tailwind

What capability, drive, or early skill is documented in the person rather than their surroundings?
Cracked the Stryktipset betting code as a teenager, becoming a betting millionaire. Started first company at 18 building ML models for sports betting (121% ROI over 5,000 bets). Bootstrapped second startup to +$1M ARR and 25,000 MAU. Worked at McKinsey and Goldman Sachs. Exceptional early achievement in quantitative betting and entrepreneurship.
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?
From Nyköping, Sweden. Attended floor hockey high school (innebandygymnasiet) in Umeå, not an academic track. No clear family wealth or domain connections. Middle-class Swedish background with no special inherited advantages.

+2Tailwind
-10+1+2+3
What place, timing, institution, or peer group made the next step available?
McKinsey and Goldman Sachs experience. Worked at two Swedish unicorns. Stockholm-based startup ecosystem. YC W26 with strong co-founder team (Tobias, Petrus, Oscar). Self-built companies from high school with no special institutional access early on.
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.
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.
Luck and unobserved varianceNo discrete luck event is documented in the reviewed biographical summaries.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Describes the starting position, not what the person later made of it.

T3 · Domain-recognized
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Oskar Block'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.

No decisive linked signal
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Oskar Block'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, Oskar Block's starting-advantage total is at the 52th 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.

Starting-advantage scores (0–2 each)
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
