Hello @Cubs27
You should check all 3 components of your sleep score: Duration (time asleep & awake), Quality (time in REM & Deep sleep stages), and Restoration (Sleeping heart rate & restlessness).
Although you slept 30 minutes less, you could have spent more time in REM & Deep sleep which would give you a higher score. If you also had more time below your sleeping heart rate & weren't so restless, that would also give you a higher score.
Hope this helps clarify what you're seeing with your sleep score.
