It is worth noting that the failure to nap after several weeks (despite adhering to the schedule by the minute and all methods have been used to facilitate napping) may be attributed to the [[Wikipedia:Basic rest–activity cycle|BRAC]] in scheduling. Since sleep pressure on E1 is generally lower than on other schedules with less total sleep, ideal nap times in which the body feel drowsiness are only at a few certain spots in the day. This can causes the nap to work poorly because the body only tired either before or after nap. The problem would be resolved if the nap is moved to those spots.

Another common issue is the rather common [[stage 3/4 loop]] for beginners. This typically happens when a sleeper cannot complete the adaptation and get stuck in [[4-Stages Adaptation Model#Stage 4|Stage 4]] where, near the end of adaptation, the sleeper feels inconsistently adapted, excessively tired at certain times of the day, or [[sleep inertia]] upon wakes. Because E1 likely has sufficient total sleep to gain all the needed SWS, being trapped in Stage 4 is most likely owing to consistently missing out on REM.

Because E1 likely has sufficient total sleep to gain all the needed SWS, being trapped in Stage 4 may be due to a slight REM deficit. A potential method to address this issue has been proposed, covered in [[#Slightly modified core length|6.5h core variant]] section.

The average time it takes to adapt to E1 is anywhere between '''4 and 10 weeks'''. The 10 weeks upper boundary is significantly higher than with many other schedules, because the process of repartitioning is slower on E1 than on many other schedules. As such, With all the available information, E1's difficulty has been adjusted to Moderate from Easy to reflect a more accurate picture of this adaptation.
