sleep first half as a nap - bug?

[martintrail]

Hi, I noticed something strange about my V2 sleep measurements. If I’m awake for a long time at night—for example, when my daughter is sick and can’t sleep—my watch measures the time until I wake up as a nap, and then as sleep and a phase. Is this a bug, or is that just how it works?

@martintrail My Vertical behaves slightly differently.

It correctly detects naps, sleep onset, and wake-up time.

However, it doesn’t seem to capture the many times I get up, sit on the bed, move from the bed to the couch, etc.

When compared with Whoop and Garmin, the Vertical tends to smooth out those awake moments and classify them as “light sleep.”
