From the manual:
"When you sleep,your body goes through a series of sleep cycles. The average adult experiences 4-5 full sleep cycles over an 8-hour period. Each cycle lasts about 90-110 minutes and comprises five different stages.
A typical sleep cycle has five stages and takes 90-110 minutes. During Stage 1 of your sleep cycle, you sleep lightly. At Stage 2, your sleep gets progressively deeper. At Stages 3 and 4, also known as “Delta sleep,” you sleep most heavily; this is when your body rebuilds itself.
Stage 5 of sleep, also known as REM (rapid eye movement) sleep, is marked by extensive physiological changes, such as accelerated respiration, increased brain activity, rapid eye movement, and muscle relaxation. People dream during REM sleep.
In the first third of the night, Delta sleep stages last longer than REM stages. As the night progresses, Delta sleep diminishes in length. By the last third of the night, Delta sleep usually ceases, while REM stages lengthen.
SLEEPTRACKER may find multiple almost-awake moments within the sleep cycle. Almost-awake moments may also vary in frequency throughout the night."
okay. sounds simple enough, right? if you'd have asked me today how i slept last night i would have said poorly. now i can say exactly how poorly. my watch claims i had
16 (average time between "almost-awake moments")

is it really terrible of me to find this kind of fascinating?
eta: okay, so now that i'm more awake, have more time, and read the instructions about data a bit more carefully, it seems i was awake a few more times than i thought because the first set of data it gives me (in this case "16") is actually the average time between almost-awake moments. hmm. i'm thinking sleep tonight will be a nice thing.
