Disagree about optimal nap length being 24 minutes for everyone. For me, when I was doing polysleeping, anything longer than about 18 minutes of actual sleeping caused my body to switch into a longer sleep cycle.
ETA: Use a Zeo to measure this. Or just go by the “time at which you naturally wake up before the 25 minutes expire”.
I disagree as well—my optimal sleep time is 19 minutes, and I take 1-2 to fall asleep, so I set my alarms for 23 and usually wake up before they go off.
I’m not sure this can be formulated in a way that “works for everybody” though. Aiming for 20 minutes of sleep and doing the picky adjustments of a minute here, a minute there after you’re adapted seems the most sensible to me.
Do you happen to know an alternative to the Zeo? I googled a bit after I read your comment and the company is out of business since 2012. But there seems to be no alternative device that measures the brain-waves to detect the different phases of sleep.

Might be able to get a used one on eBay.

I am not sure I want a device that has no longer any support :/
But the Zzzs thing sounds really cool, I just reserved one for 15$. Thanks for the links!
