I can't understand why intensity minutes are device specific? GC soft/app has all the HR data related to your workouts, all minutes above your normal HR should be counted as intensity minutes. Why it isn't happening, can someone explain?
For example, I have two devices - 920XT and Vivoactive HR. I have 5 workouts per week on XT and none on VAHR. In the end I have 0 intensity minutes per week :D Where is the logic?
