@MarkusG big problem of our modern society where everyone can just spread unverified and anecdotal information! Better rely on verified data from independent researchers and experts. But apparently there is too much money to make with just claiming that you have developed something special. Garmin is the worst example with their “body battery”, “heat/height acclimation”, “Real-Time stamina”, “endurance score”, “training readiness”, “running tolerance”, “race predictor”. Nothing of that has ever been scientifically validated that it actually works and every good coach and athlete can do more accurate race predictions
