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 Kodi Smit-McPhee 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?
Started acting at 9, feature debut at 11 in Romulus My Father winning AFI Best Young Actor. Booked emotionally demanding adult roles (The Road at 12, Let Me In at 13) with no formal training, relying on father's coaching.

What money, family standing, network, or permission was already in place before the work began?
Father Andy McPhee is an actor and former professional wrestler who coached Kodi on set and introduced him to acting. Sister Sianoa is an actress (Neighbours, Hung). Family-domain apprenticeship with father as direct mentor.

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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Kodi Smit-McPhee'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, Kodi Smit-McPhee's starting-advantage total is at the 95th percentile. Separately, their built or converted leverage total is at the 51th 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.

Evidence summary
Smit-McPhee grew up in an acting family — his father Andy McPhee is an actor and former professional wrestler, and his sister Sianoa is an actress. This family-domain apprenticeship gave him early entry into acting at age 9, leading to a feature film debut at 11 in Romulus, My Father alongside Eric Bana. He dropped out of high school to pursue acting full-time, demonstrating extreme concentration intensity. He was diagnosed with spondylitis as a child, which may have created urgency and a distinctive perspective. His years of child acting in Australian and American films built exceptional prior reps before his adult breakout in The Power of the Dog.
