Time in HR zones missing data

Former Member over 8 years ago

After a long activity this weekend, I was curious to see how much time I'd spent in each HR zone, and noticed that there's a lot of time missing from the chart. And the percentages don't add up to 100%. I've exported to TCX and converted to CSV so I can attempt to graph and validate for myself, but I'm no data wizard; that's going to take awhile. >.<

That said, it doesn't take a data wizard to see this isn't right.

Best I can tell, there's about 5.5 minutes at the beginning of the activity where I'm below zone 1, so that accounts for some of the missing time, but not anywhere near all of it.

Well, I managed to crunch the data together to get the amount of time spent in each zone, in seconds and by percentage. I'm not sure how Garmin is calculating the data, and there's not much sense in me posting the data here, but they're definitely missing something along the way.
