The other day I configured custom training zones for running and riding, but I "forgot" to configure the "default" training zone. Why "forgot"? Because I thought that If I run or ride, the custom zones were going to be used instead of the default one. To my surprise, when I uploaded a run activity to Garmin connect, the "Time in Heart Rate Zone" graph was using the default (and unconfigured) zone to show the results :-O I checked my watch in order to verify if the zones were Ok. Yes they were Ok. Also, I started a new run activity and I could see that in the watch the heart rate zone widget was using the custom run zone, but again, after the upload, the Garmin connect used the default one.
My questions is: Is this a expected default behavior? How about the fitness algorithms?, do they use this data? and if so, data from the default zone of from the custom ones?
3.30 is my firmware version.
