Dual Core 3, or DC3, is the third dual core schedule, following the sequence of the [[Dual core|Dual Core family]] with further sleep reduction in both [[Cores|core]] sleeps, both of which now only have 1 full cycle, with the addition of the nap around sunrise hours.<ref name="polysoc" /> The total sleep of the whole schedule is 4h, which is also the bare '''minimum sleep threshold''' that an average person (~8h monophasic) should be able to adapt to.{{TNT|DC3}}

{{TNT|DC3}}'''DC3''', or '''Dual core 3''', is the third dual core schedule, with shortened [[Cores|core]] sleeps, and three naps throughout the day.<ref name="polysoc" /> With the standard variant, the total sleep of the whole schedule is 4h, which, along with the divided cores, makes it one of the most difficult schedules that an average sleeper may be able to adapt to.

The core sleep in the SWS peak as usual will heavily favor [[wikipedia:Slow-wave_sleep|SWS]], while the second core sleep will contain some more SWS and invite some [[wikipedia:Rapid_eye_movement_sleep|REM]] sleep as well. The primary reason is that the first core will not be able to cover all SWS requirements (assuming ~90m SWS need each day) and the second core will be required to complete the task. Given the low total sleep, to ensure quality SWS, the first core always has to lie within the SWS peak. The remaining naps, being in the daytime hours will most definitely store a lot of REM sleep to support sufficient REM baseline, ideally. However, the last nap, located in mid-afternoon hours (~4 PM), may not always guarantee REM sleep. REM sleep will hugely be accumulated in the first nap around dawn, which will generate a lot of vivid and intense dreaming when adapting.  

As with other Dual core schedules, the first core should contain mostly [[wikipedia:Slow-wave_sleep|SWS]], while the second core sleep will contain mixed sleep stages, due to its early placement as well as the inability to gain all of the SWS required during the first short core. Given the low total sleep, the cores should be scheduled close to the SWS peak to ensure the preservation of SWS. The first nap is placed early in the morning, and will likely contain mostly REM sleep, whereas the other two naps may contain a mixture of light and REM sleep, along with trace amounts SWS.

In order to schedule DC3 effectively, both core sleeps will have to be moved closer together to avoid as much daytime sleep as possible; this will limit the number of daytime naps to 2 per day (noon & afternoon). So far, the default variant is the variant that reported some successes; adaptations to DC3 are very rare due to the more sophisticated split-sleep mechanics of a Dual Core schedule, and it is largely '''overshadowed by [[E3|Everyman 3]] (E3)''', especially the variant with a 3.5h core sleep.  

Compared to other dual core schedules the two cores are placed relatively close together, which helps spread sleep more evenly during the day to ensure alertness on a schedule with such low total sleep.
