Sonar Sleep HRV doesn't match data source from Garmin

The sleep HRV data from my Garmin differs from the display in Sonar. Just as an example see data of the last four days: 43 44 44 43 (Sonar) vs 48 48 49 47 (Garmin). In the beginning it seemd that data form Garmin were mirrored in the Sonar app, but at some point weeks ago that changed. Since there is no other source of HRV data configured and I also blocked the export of HRV data from Apple Health I have no explanation for the situation. I do record HRV data in Apple Health from a Polar H10, but the only data granted for export are BPM data. I also have the Elite HRV app on my phone, which I use to measure the morning readiness data, from which the SDNN value is shared to Apple Health, but the Elite app is not configured as a data source in Sonar. To me it looks like the final data in Sonar were averaged with some other data, but there is no configuration that would allow that.

It doesn't mach for me either.

Stefan Riegler: do you have any other data sources synced with Sonar that would be providing HRV data, or only Garmin?

Only Garmin, this night 41 (Sonar) instead of 44 (Garmin) average

Stefan Riegler: It's likely Garmin is sampling a different portion of the sleep session than Sonar does, but it is strange that for JP it used to match, as we haven't made any changes in logic there for months.
Would you mind sending some logs for us to investigate further? To do this, just navigate to the Profile tab, scroll down to the bottom, and tap 3x quickly on "Version." This will reveal a "send logs" button. Appreciate it!
