I had a garmin device available in the pool today, and wanted to test it for a swimming activity. But the import to Runalyze is a bit odd. Heart rate and cadence profile doesn't look right, and aveareage and max heart rate values are wrong. In this example heart rate average/max are 127/150 in garmin and 133/145 in runalyze, heart rate profile is somehow binear in runalyze, and cadence in Garmin is around 17-23 while in runalyze 29-36. When importing the same fit-file to strava I get similar heart rate plots as in garmin.
Is there something wrong, or have I some errors in a setting somewhere? Or have I missunderstood something?
I have attached a screenshot of garmin vs runalyze:
