Slightly better...

I'm already running into a construct validity issue here (where there is a gap between the measured construct and the reality it's supposed to represent). Both going to bed and getting up are often not continuous processes for me, and the data simplifies this away.
Last night I laid in bed for a while, still in my clothes, before thinking, "Alright, let's actually go to bed" and got back up to brush my teeth and stuff.
And this morning, I got out of bed still in my nightclothes, did some things, then went back in for a bit.
In both cases, the data only captures the final timestamp when I'm "fully" in bed / up.

"eqyo, why are you turning everything into a science rant" I know, I know, I'll stop, I see looking at the clock that I should've turned this thing off 9 minutes ago, anyway.

(Compared to how it often goes on weekends lately, this is quite good)

Quite a bit worse last night:
00:45

Still an improvement compared to one week ago, though

So last night was:

For the 5 days before that, I've got no data because I kind of went off the rails. Let's see, I worked through the night mon-tue (did lie down for a bit in the morning), the rest of them is all bedtimes around 2 or 3 o'clock, I believe.

@eqyo if you collect several years of such data then you can analyse the correlations between the sleep patterns and the other aspects of your lifestyle or external events.

(but despite having such datasets & analyzing them multiple times my bed times are still a terrible mess...)

@vleugelcomplement I've been tracking my sleep schedule for a while now, though in less detail and on paper. Never though to do statistical analysis on it.

Posting it publicly like this seems to be having some effect, it definitely feels different; I'll see if it lasts.

@vleugelcomplement
* Never thought

@eqyo Guess having your computer turned off early is not a guarantee you go to bed early as well. :)

@trinsec Yeah, it just so happens that on thursdays I get back home around 23:45 and on other days earlier.

@eqyo Well, there's somewhat a consistency. But do you really sleep 10 hours a day on average?

@trinsec No, for me there's a huge difference between lying in bed and sleeping, I tend to lay awake for hours before dozing off 😦
