I've made a tour with bycile and foun out, that heart rate zone time is not a same as hear rate time in total. check attached picutre. Any idea why?
Total time in graf is 3:41h. Total time in HR Zones is 1:38h. At 2:44h i've presed a piuse. But still... some time is missing. I am using edge explorer 2 and HR belt
