Sleep data

Question

I have had my Garmin for about a week. My sleep report and data will display the different levels totals but as the day progresses those totals will change. For example, my deep sleep will come in at 2hours in the morning and then if I relook at it in the afternoon, it might show as 1 hour. This is happened at least for three days. why is this happening?

This is actually the standard behaviour. The sleep data is being processed on the server, and during the day the analysis may continually change. Hard to tell whether it is because the analysis uses some self-learning algorithm permanently adjusting, and improving the the analysis, or whether it is rather a bug. Some people suspect that the sleep data may be simply generated by a random generator, and have nothing to do with reality. There are several threads with this topic, here on the forums, but I did not hear yet any official statement of Garmin to the issue.
