E5 is similar in structure as other Everyman schedules, having 1 core sleep and more than one nap. However, similar to [[E4]], E5 can create an impression of a [[nap-only schedule]], as the core only has 1-cycle duration, and a 90 m duration is often mistaken for a nap outside polyphasic sleep's context.

The core will contain the bulk of [[SWS]], and the naps will relieve [[REM]] pressure and sustain alertness. They are spread throughout the day, looking somewhat equidistant from one another to resemble Uberman sleep (~3-4h wake between each sleep). Because of having a plethora number of naps, one nap is located in the middle of the [[graveyard hours]]. This makes the adaptation to this schedule by itself, or even just a temporary transition a very sophisticated process. As '''core body temperature drops around nighttime hours''', where sleep is facilitated, core sleeps are preferred over short naps. It is expected that SWS likely will enter this nap in the case of normal SWS requirements. The latest nap in the day, located around late afternoon/early evening hours (~6 PM) may also contain SWS because of the high sleep pressure formed by the very low total sleep. After adaptation is completed, presumably the '''core cycle length can reduce to ~60m''' because of the high frequency of naps that contain REM sleep and mostly SWS and traces of light sleep go into the lone core.

The core sleep cannot support a regular amount of SWS requirements (~90m), and when vital sleep is [[Repartition|repartitioned]] into each sleep block, any naps in the day can generate [[SWS wakes]]. Once REM pressure builds up, adapters will have to manage the intense [[sleep inertia]] from each REM wake. Long crashes can occur frequently during adaptation due to SWS wakes, and [[4-Stages Adaptation Model|stage 3]] is expected to arrive only a couple of days in, because of a '''gargantuan sleep reduction''' from an average monophasic baseline (8h).

With the high density of sleep across the day, initially it will be difficult to fall asleep in many naps in a row, as on any other polyphasic schedules for beginners/non-nappers. Then, this would increase the chance to oversleep in the late nap in the day, or the core sleep the following day(s). Despite having 20 m of extra sleep compared to E4, the extra nap only serves to somewhat provide more alertness, and as adaptation progresses, this extra nap can become a liability (an extra opportunity for a nasty SWS wake). Any oversleeps would endanger the adaptation in a much greater magnitude than on schedules with higher total sleep, because it is mandatory to overcome the equilibrium of SWS and REM sleep in each sleep block to be able to adapt.
