Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
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.
Notable, but primarily known within a niche. The tier summarizes documented career recognition through the data cutoff—not Danny Makkelie's worth or future potential.
Question four · where did the leverage come from?
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.
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.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Danny Makkelie's outcome attributable to any origin.
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 Willemstad, Curaçao to a Dutch Royal Marine father; family returned to the Netherlands when Makkelie was young; father was supportive and drove him to matches.
Father was a Dutch Royal Marine who encouraged and supported his refereeing path, driving him to matches, but had no professional refereeing domain expertise.
Makkelie was born in Curaçao and moved to the Netherlands as a child. He began refereeing at age 10, taking charge of football and basketball sessions, and progressed to adult matches as a teenager. His father, a Royal Marine, was his biggest supporter and drove him to matches. He was invited into the KNVB refereeing system and refereed his first professional match at 22, making his Eredivisie debut at 26. His path was driven by self-created domain repetition from an exceptionally young age, with the KNVB pipeline providing institutional structure.
