Mine says 68 today. Green zone apparently. But 68 out of what? Compared to what baseline? Why 68 and not 71? Should I train hard or take it easy? The app doesn't say. It just shows me the number and a vague color.
Most wearables give you a score with zero explanation of how they got there. Black box. Proprietary algorithm, tuned for some average user that probably isn't you. You either trust it or you don't, but you have no way to verify it either way.
