”[The twins] realized they possessed the ultimate scientific tool: a perfect control subject and a perfect variable. Ross wore modern kit while Hugo wore historic replicas. Any difference in performance could be attributed solely to the gear, not genetics.” It’s a great idea and these men are undoubtedly incredible athletes, but I’m not sure “ultimate” and “perfect” are the right words here. A killjoy would bring up double-blinding or n>1 and I don’t want to sap the fun out of this being about an interesting people-centric piece. There’s no mention though of a more basic trick: having them alternate clothes every expedition or season! Pfizer it ain’t, but it would still take it up a notch on the scale of interesting/fun to “ultimate/perfect”.
