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.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Jan Raas'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.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Jan Raas'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."
Not documented in reviewed sources beyond being born in Heinkenszand, Netherlands.

Raas turned professional in 1975 with TI-Raleigh, a top Dutch cycling team, under the mentorship of director Peter Post. His natural sprinting ability and tactical sense led to rapid success: the Dutch National Championship in 1976 and his first Monument at Milan-San Remo in 1977, both before age 25. The Dutch cycling ecosystem and the strong TI-Raleigh team structure provided the competitive environment for his early breakthrough.
