How is it calculated "Time Asleep" on Inspire 3?

[tidj]

Hi, I would be curious to know what is the formula or at least the input variables of the "Time Asleep" score.

The reason I am asking is because when comparing my Wednesday and Friday scores, I can observe a difference of 3 min in time Asleep, but a different of 4/50 in score.

I feel the 8% difference (4/50) pretty big for only 3 min of difference in time Aleep.

Thank you

Wednesday:

- Time Asleep: 7h53 min

- Awake: 1h8 min

- Score: 42/50

Friday:

- Time Asleep: 7h56 min (+ 3 min)

- Awake: 1h8 min (-1 min)

- Score: 46/50 (+4/50)

Hi, @tidj, thanks for the feedback, you could try talking to "Customer Support" using the phone or chat facility for a prompt response. I think you will not get any further information from the agent as there will be a limit to how much of Fitbit's propriety algorithm is made public.
