Even though E1 looks to be a straightforward polyphasic schedule to start with for beginners and non-nappers, the adaptation results from E1 adaptations in the community over the years do not reflect the notion that E1 is supposed to be an "easy" schedule. There have been many reported problems from beginners over the course of adaptations that prevented them from reaching the adapted state: inability to fall asleep in the nap despite several weeks in, high sleep onset for the nap after many weeks, or in some rarer cases, oversleeping from the nap consistently (which may suggest that these sleepers have a stronger tendency for a daytime core rather than a short nap, as an example). All of these issues, however, can be attributed to sleep debt prior to starting E1 adaptation, poor discipline, poor alarm system, or wrong assessment of personal monophasic sleep need (high sleep need which increases the difficulty of E1 to great magnitudes).

Probably the most troublesome issue is the rather common "<u>stage 4 loop</u>" for beginners. This typically happens when a sleeper cannot complete the adaptation and get stuck in '''Stage 4''' (near the end of adaptation, feeling inconsistently adapted, or excessively tired at specific hours of the day, or not truly refreshing sleeps overall). Because E1 has a high total sleep compared to other more advanced polyphasic schedules, being trapped in Stage 4 is most likely owing to consistently missing out on some vital sleep stages (typically REM sleep is being missed since only the last full cycle of sleep is removed) or the nap fails to give consistent REM sleep, or no REM sleep at all.  According to the Polyphasic Survey 2018, only '''50% of E1 sleepers managed to get REM in their nap'''. This in return demonstrates that the sole afternoon nap does not guarantee to deliver REM sleep (trace SWS, or mostly NREM2 instead) and can result in an incomplete repartitioning of REM sleep and the failure to obtain a sufficient amount of REM sleep each day. The overall time it takes to adapt to E1 is anywhere between '''4 and 10 weeks'''. With all the available information, E1's difficulty has been adjusted to "<u>Moderate</u>" from "Easy" to reflect a more accurate picture of this adaptation.

This in return demonstrates that the sole afternoon nap does not guarantee to deliver REM sleep (trace SWS, or mostly NREM2 instead) and can result in an incomplete repartitioning of REM sleep and the failure to obtain a sufficient amount of REM sleep each day. Based on the data above, it is still possible to complete the adaptation to E1 with no REM in the nap as this is not a requirement. The overall time it takes to adapt to E1 is anywhere between '''4 and 10 weeks'''. With all the available information, E1's difficulty has been adjusted to "<u>Moderate</u>" from "Easy" to reflect a more accurate picture of this adaptation.  

If the adaptation to E1 is completed after a reasonable amount of time (within 2 months), it is possible to proceed to E2 and E3 as parts of the Everyman schedule line as a gradual adaptation method.
