Another viable alternate variant with some success is a late core. Sleepers with less SWS requirement and somewhat higher REM requirement may benefit from this scheduling, as some hours of the core now lie in [[REM peak]], which will boost the amount of REM gained during these morning hours. Night owls or those who prefer some social time in the evening may also benefit from this variant. The nap can be placed ~6-7h after the core like in the default variant, or later, but should not be too late into the day (6 PM or later). | Another viable alternate variant with some success is a late core.

Those with a tendency to sleep early as a long-term habit can place the core around the late evening hours, initiating sleep time early. The nap will then be shifted accordingly, earlier than the default version. Sleepers with high SWS requirement can also utilize this distribution. The earlier nap can also give more REM sleep, being in the morning hours that are more likely to allow for REM sleep. | Those with a tendency to sleep early as a long-term habit can place the core around the late evening hours, initiating sleep time early (e.g. 20:00-21:00).

However, because of a high total sleep, it may take a long time to finally be able to fall asleep in the nap compared to standard E1. The adaptation to E1-extended may last just as long as the regular version, but with a much milder adaptation and possibly [[Special:MyLanguage/4-Stages_Adaptation_Model#Easier_adaptation|silent stage 3]], with no signs of severe [[wikipedia:Sleep_deprivation|sleep deprivation]] symptoms or crippled productivity as seen on other more reducing schedules that has been observed in successful adaptations. Picking this variant as a result may give the benefit of potentially maximizing daily performances (physical and cognitive) at work and/or school even when adapting. | However, because of a high total sleep, it may take a long time to finally be able to fall asleep in the nap compared to standard E1.

{{nci|qptxq|right|E1-shortened}}This variant has a shorter core, 5 hours or less, which usually consists of 3 sleep cycles. One of the most popular proposed forms is 5h + 30m. Similarly to Siesta, the 3-cycle core is extended to 5 hours, which allows to get more light sleep and REM for sustaining E1-shortened. The nap is extended to 30 minutes, which further increases total sleep time and should make the schedule more sustainable. | |||
This schedule is more difficult than the standard one, but might be possible for those with a lower sleep needs (~6-7h on mono). | |||
