My Instinct does much worse at tracking my HR than my old Vivo HR did. I am only getting about half of the activity minutes from my bike rides. The peak HR from my Instinct is usually lower than the average measured by my chest strap going to my Edge510. The chest strap will measure 150 avg and 175 peak, the Instinct will be 110 avg and 140 peak. Is there a way that the activity minutes calculation can default to chest strap data if available? It is all uploaded to Garmin Connect anyway.
