Translations:E3/10/en

Because of the reduced total sleep, each nap on E3 will not sustain wakefulness for a period as long as the naps on E2 or one of the extended variants with higher total sleep. The ideal wake gap from the core to the first nap is anywhere around 3-4h, 4-5h between the first 2 naps, and then up to ~6-7h for the last two wake gaps. In successful adaptations, the first two naps primarily contain REM, and the third nap may also contain mostly light sleep.
