Hm, right. So the really deep SWS sleep seems to mostly happen during the first 3 hours of sleep, and the rest is alternation between REM and lighter sleep. Based on that, the Everyman cycle does look a lot more sustainable than full-on Uberman.
And, your body repartitions your sleep on a polyphasic schedule. My sleep really isn't like yours any more. See the bar charts waaaay down the page here: http://trypolyphasic.com/forum/post/8455/#p8455
This is the public group instrumental rationality diary for the week of August 20th. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes!
