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 Alex Tan 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?
ROM hacking and level design from a young age, created Guinness World Record-holding Super Mario Maker levels, completed Super Mario World blindfolded. Exceptional technical skill and memorization in a niche domain.

What money, family standing, network, or permission was already in place before the work began?
From Rocky Hill, Connecticut. Father allowed use of his YouTube account, fostering early online exploration. Attended Greater Hartford Academy of Math and Science (half-day program) and Rocky Hill High School. Middle-class, stable family.

Part of the online ROM hacking and speedrunning communities. Super Mario Maker platform provided a creative outlet. University of Connecticut for college. Online community was the primary peer group.
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.

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 Alex Tan'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 Creators / artists, Alex Tan's starting-advantage total is at the 13th percentile. Separately, their built or converted leverage total is at the 27th percentile. Other T4 profiles average 5.9 / 24 starting advantage and 10.4 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
