my conclusion

Heh I can definitely swing a 20 minute siesta since I work from home

I'm buoyed by the fact that my roommate has been doing this forever. He takes his nap on his lunch break ideally, but sometimes in the afternoon if he doesn't have meetings

Will a 20 minute siesta really make it so I only need 6 hours of sleep at night?

Not sure. But I can easily try this out and test it.
