You might find some of the writings on supermemo.guru regarding sleep interesting.
SuperMemo is a spaced repetition app (it was the very first in fact) that has a thing called sleepchart built in. It lets you both track sleep for finding interesting patterns alongside getting altertness/cogniti8ve data from correlation of say hour of day vs. average grades:
There are a bunch of confounders (they could be eliminated were I more rigorous) but I think it’s interesting and even without SRS data I get some useful data:
Basically red line is how long sleep episodes are, blue line is how frequent they are around that time. You can see there’s a peak around 6 hours from waking and around 16⁄17 hours from waking. The green line shows breakeven (if I sleep at that time, for the amount of hours on the left, it’ll add up to 24).
It’s probably really complicated looking but if you want to try it let me know and i’m happy to show you how. Doesn’t take long to learn and takes very little time to add track in a new sleep episode.
