E3: Difference between revisions

Nowadays, this core length has been '''more commonly used''' for an E3 adaptation rather than the 3h core. The total sleep is similar to [[Triphasic]], hovering around a more comfortable sleep total for experienced or highly motivated attempters. The same principles that apply to the 3h core also apply to a 3.5h core. The core sleep should not start any later than 10-10:30 PM, to retain sufficient amount of SWS. If all SWS has been accounted for, the +30m from 3-3.5h mark can give more light sleep or REM sleep, to match personal REM baseline more comfortably. This is also a core duration that is popularly used in [[Segmented]] sleep and scheduled in the SWS peak for the same purpose. The naps are scheduled in a similar manner. It ''may'' be possible to '''gradually''' '''transition from Segmented sleep''' (with a 3.5h first core), a scheme proposed by '''[[Polyphasic Society]]''' to get to E3, but it is unknown if anyone has been able to pull this off.  

The benefits of this variant is the '''flexibility''' of the core sleep after adaptation (~15-30m earlier or later than the original time should be realistic), and the flexibility of the last nap, or the second nap as well. Contrary to other polyphasic schedules with 4-4.5h total sleep, this 3.5h core version seems to be the most flexible. However, adaptation remains very punishing for any oversleeps as long as ~1h at least. The exhausting process of repartitioning will also ramp up around the second or third week. Those who want to start a first polyphasic adaptation should aim for this variant to stay at a safer amount of total sleep, and a somewhat milder adaptation than the original version.
