For 9-to-5 occupations, which are very common nowadays and do not allow any naps during lunch breaks, it is possible to schedule this E1 variant with a nap after work (~4-5 PM) and a core around midnight or slightly later, with a dark period 2h before the core. However, there have been less success with this E1 variant, because the late nap has a low chance to give REM sleep, being in late afternoon and closer to SWS peak. This can make adaptation harder than the default variant. The long wake gap in the day and until the nap can give a few tiredness waves during adaptation. A morning person can still take advantage of this E1 distribution of sleeps.

Another viable alternate variant with some success. 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. Those who prefer some social time in the evening or have a strong tendency to be alert at late hours in the day can also schedule 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).

Recently, a '''new''' core length variant (6.5h core) has been proposed and has been delivering '''solid adaptation results''', even though only few sleepers have decided on this variant. With the idea that SWS mostly occurs in the first half of the night, and REM dominates the second half, after the 6h mark (which is the end of the default E1 core), there should be very limited, if not none, SWS. This will open up for more REM sleep and/or NREM2 to get into the core, to boost alertness and provide a better opportunity to match personal REM requirement on monophasic.  Similar to a 5h core (seen on Siesta and some Everyman variants), the +30m addition to the core is also considered a '''statistically likely REM period''' on a 6.5h core. Individuals with slightly higher REM sleep than usual (> 100m each day) can attempt this variant. People with overall higher sleep need, or close to adulthood can also pick this variant for a closer total sleep to recommended monophasic baseline. A 6.5h core is also a strong compromise between the potentially difficult 6h core and the lengthy 7.5h core which offers less sleep reduction. Despite the promising adaptation results, more data samples need to be collected for this E1 variant to discover any potential weaknesses it may have, however.
