Despite the biphasic nature (which bears resemblance to monophasic structure), adaptation to E1 follows the same rules as any other reducing polyphasic schedules; this means that it is necessary to go to sleep at the same time everyday for the nap and the core for the new sleep habits to stick. '''Exceptions''' are made when the total sleep on E1 (6.3h) is very close to, or the exact same as personal monophasic baseline - these individuals can then proceed to have a flexible nap while keeping a somewhat flexible core sleep from day to day, without having to stick to the sleep times by the minute during adaptation.

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).
