E1 with a nap after work

For 9-to-5 occupations that 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 has been less success with this E1 variant, because the late nap has a low chance to contain REM sleep, being in late afternoon and closer to SWS peak. This can make adaptation harder than the default variant. The long wake gap before the nap can cause bouts of tiredness during adaptation.
