Changes

With the common trend to schedule the E1 core at 11 PM or midnight-ish (with good management of dark period, food and exercise), E1 does offer versatility in scheduling. A lot of variations have been tried, succeeded and even maintained for an extended period of time (at least 6 months) by a couple E1 sleepers. It is wise to consider these options before deciding on which scheduling variant to try.

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. An early riser 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).
