We get about as much REM and SWS (deep sleep) as monophasic sleepers - about 90mins each per 24hrs. This is one hypothesis to explain why so many people (me included) have so much trouble adapting to the original Uberman schedule (which, properly adapted, gives you 50+ mins each).

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
