How does this happen? I have included a screen shot. If you look in the upper left corner area, so can see that my average HR zone was 4.8 and the highest recorded was 5.6. This appears to be correct based on what my 610 was saying. BUT, if you look at the graph with the average line, there is no way the chart is correct, right? The line is at 4.8, but it seems WAY above were the heart rate lines are.
This phenomenon was way worse on some other runs. On those, the above issue was present, but also the max recorded was 5.1, but the heart rate chart didn't go higher than 4.5 on the graph.
Any way to repair the analysis GC is doing on only some of these runs?
