This morning I noted a discrepancy between zone minutes and heart rate. Heart rate showed a range of 54 low and 89 high. Zone minutes showed a total of 23 zone minutes. Zone minutes showed the minimum moderate activity heart rate to be 95 based on a resting heart rate of 61, which was displayed in the heart rate Tile. At one point during my session monitoring heart rate on my iPhone I noted that the heart rate was fluctuating in the neighborhood of 112 bpm. This is considerably Different from the 89 high shown in heart rate range. I am assuming that zone minutes and heart rate, although using different terminology work together. Zone minutes identifies heart rate, zones as light, moderate, vigorous and peak, where in heart rate zones are identified as fat burn, cardio, and peak And within exercise days when you click on an exercise session, you will also note that it is broken down based on fat burn, cardio and peak. I can only assume that the two different terminologies are related and we know what assumption means. Can anyone explain why  The range within heart rate does not correlate with zone minute activity.

I am always confused when the zone minutes and heart rate minutes are different. For example it will say 20 fat burn zone minutes, but in the heart rate, it will only show 10 minutes fat burn. I am very confused and annoyed by this. I also do not like that Fitbit calculates calories burned while at rest. I am interested in the fitness part only. I do not care or need to know that I burned 200 calories just breathing and working at a desk.
