I usually track my sleep data with my watch but I fell asleep with it off. Yet it informed me of sleep data anyways. How did this happen? Was this just a rough calculation based on previous nights where I wore it?

It calculates the time based on when sleep focus was turned on/off and when you used your phone during that time. I don’t usually wear my Apple Watch to bed and still get the “time in bed” data anyway.
