Hello, I have a question about the Time in Heart Rate Zones bar graph and the Heart Rate line graph. It seems that mine do not match up. If you look at a screenshot of my Fitbit after a cross country ski, you'll see that my heart rate line graph shows I had an average HR of 126bpm with a max of 146bpm. There's only a little bit of time in the blue (below zones), lots in the yellow (fat burn) and a bit in orange (cardio). However, my Time in Heart Rate Zones bar graph says I only had 8 minutes in fat burn and the rest was below zones. This doesn't seem right to me. Am I missing something? Is there a way to fix this?
