HRV daily RMSSD

[acbowz]

I am looking at daily summaries from the daily summaries of HRV data.  and I am a bit confused about the output. 

{
      "value": {
        "dailyRmssd": 62.887,
        "deepRmssd": 64.887
      },
      "dateTime": "XYZ"
    }

 What is the data used to calculate the "dailyRmssd"? Is data from the current day included or it the previous days data used?

For example: Is the daily rmssd for a given day based on data recorded during that particular day or is it based on data during the day on the day before?

Hope someone can elaborate 🙂

Hi @acbowz 

HRV is recorded during a user's sleep period, which can span over 2 days.  The date represents the date when the sleep log stopped recording.   So, the information in the response could cover 2 days if that is the time period of the user's main sleep.
