Up to date there has only been a success or two with this scheduling. The concepts look similar to the default version, except for the nap placement. There is a slightly longer wake gap between the sunrise nap and the noon nap, which allows for more wake time in the morning to maintain an uninterrupted and longer work flow. The last nap is moved to after regular work/school hours (which is usually around 5 PM). Due to the low total sleep and a shortened core, it is necessary to schedule the naps somewhat close together, as one nap will less capability of sustaining wakefulness. A 20m nap on E4 will not fuel performance as long as a 20m nap on E3 or E2 for that reason. Thus, it is not advisable to have more than ~'''5h wake gap between any naps''' (barring the last nap's wake gap) on regular E4 scheduling

One polyphasic sleeper from the Discord community has successfully adapted to this variant. This E4 is basically '''E3 (3.5h core variant) with an extra nap'''. The extension of the core sleep creates a lot more space for SWS and REM, and alleviates the pressure on the naps. Same as the regular version, 2 naps are moved to night hours before the day starts, leaving only 2 daytime naps. Alternatively, a '''3h core''' is also viable, but it has no adaptation success, and flexing a 3h core on an Everyman schedule is already established to be very unlikely.
