Who else races

The control comes first

So the same scan was run twice. Once against the real archive, and once against 22,383 people who do not exist — the archive’s own first names recombined with its own surnames, in the same proportions, paired so the result is nobody. Jean MARTIN’s first name onto Pierre DURAND’s surname.

Whatever rate the decoys match at is the coincidence floor. If the real people matched at the same rate, there would be no finding here at all.

Triathlon, road and mountain — the 60 listed

Only people whose name appears once in each roster it matched are named. If “MARTIN JEAN” appears twice in the Paris marathon, attributing it to one Alpe finisher is a coin flip, so those matches are counted above and left out here. 2,587 matches were dropped from the list on that rule.
