Over the last week my SpO2 sleep average has jumped from about a 92 average to a 96 to 97 average.  This roughly correlates with the last OS update.  I wonder if any one else has noticed this type of higher estimate of SpO2 while sleeping.  I’m wondering if Fitbit changed the algorithm for this measurement.
