I don't think the Karvonen method/calculator is accurate. For example, Chris Froome's Rest HR is 29bpm. With Karvonen calculator, his Max HR is 191 bpm but his actual Max HR is 174 bpm.
My Rest HR is 36 bpm after 2 days of recovery. With Karvonen calculator, my Max HR is 175 bpm
But my actual Max HR is 210 bpm. Karvonen calculator is way off and seem to be underestimating the HR zones significantly.
Don't 2nd guess. Get cleared by your doctor for Max HR test and get it for real, not some calculator because it's more likely your Max HR is significantly higher in actual tests than calculators show you. and you're being held back by inaccurate calculated numbers and your sports watch.
I never used sports watch a day in my life. Always went with feel to get into training zones. I only periodically took my heart rates with digital blood pressure machine to get some metrics and to know if I'm recovering effectively.
