The ×10 trick is the scale's origin story — Borg anchored 6–20 to the 60–200 bpm range. RPE earns its keep where HR misleads: heat, caffeine, dehydration and cardiac drift all push HR up without extra training stress, while the legs' honest report doesn't lie. Strength training borrowed it too (the modern 0–10 'RIR' variant).
