Actually today and yesterday's data synced correctly from Garmin, and I already corrected the data in calistree from the ~ 4 days prior but I'll share what it shows from Sunday in case it's still helpful (I can't remember what the distance in calistree had been prior to my manual edit but usually it is roughly but not exactly double the actual distance). I also found an entry from ErgData that exhibits the issue and attached that. I thought it might have been due to syncing between other services, but I've removed activity writing from Strava and Google Fit to Health Connect and the issue was still happening. The issue is quite consistent (although of course it stopped the moment I posted about it 😆) and as I alluded to, is often roughly double the distance I actually achieved.

Jordan C From what we've seen so far, that's generally an issue due to the other app and what data they send to Health connect, rather than a mis-read from Calistree.

To verify, please open Health connect on your phone (open the settings and type health connect in the search bar) and look for the data received from Garmin connect and ErgData. Please screenshot the data they send (and that led to the wrong values in Calistree) and post it here.
