Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Peter Karlsson against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+1Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Started playing table tennis at 7 with his brother on the kitchen table. Was not a standout junior (sat on the bench at the 1986 European Youth Championships). Above-average ability that developed through systemic training rather than prodigy-level talent.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Grew up in Stenstorp, Sweden. No notable family table tennis background. Brother introduced him to the sport. Working-to-middle-class family with no documented domain connections.
The shape of the track
+3Tailwind
What place, timing, institution, or peer group made the next step available?
Part of Sweden's golden era of table tennis alongside Jan-Ove Waldner, Jörgen Persson, and Mikael Appelgren — a once-in-a-generation peer environment. The Swedish table tennis system provided elite training and competition. This peer group was trajectory-changing for his development.
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.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Elite institution pipeline, Frontier geography, Exceptional peer / cofounder.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Domain proximity, Started serious reps before 20.
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 and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Peter Karlsson'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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Peter Karlsson'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 Stenstorp, Falköping, Sweden. Started playing table tennis at age 7 with his brother on the kitchen table. Not from a table tennis family.
Not documented in reviewed sources as having a family table tennis background.
Karlsson started table tennis at 7 with his brother in Stenstorp, Sweden.
