You need to have an alarm clock or sleep tracks that will mechanically wake you up after 20 minutes. You go to deep sleep if you sleep over 30 minutes, and then you start getting sleep inertia and messing up your night’s sleep.
I just set the clock to something like 25 minutes and lie down. It seems to be more refreshing than staying up even if I don’t end up falling asleep. If I do fall asleep, even five or ten minutes of sleep seem to help quite a bit.
For me the failure mode is the naps becoming too long. Taking naps too late makes it impossible to sleep in time for me, too.

This is true, but since I can’t reliably predict how fast I fall asleep, I can’t set the time properly.
Most of the times would just end up lying awake, and not feeling refreshed afterwards.
