DC3
DC3, or Dual core 3, is the third dual core schedule, with shortened core sleeps, and three naps throughout the day.[1] 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.

Mechanism
As with other Dual core schedules, the first core should contain mostly 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.
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.
Adaptation
One can start gradually adapt to this schedule from TC2 with modified timings, replacing the last core with a nap, while preserving sleep placements. Alternatively, transitioning from DC2 or DC1 also possible, but have seen no successes.
Starting the adaptation cold turkey has reported at least one successful adaptation. Regardless of the adaptation pathways, all sleepers would need to go through the intense repartitioning of vital sleep stages to be able to adapt to this schedule.
Difficulty
DC3, with its 4 hours of total sleep, is very hard. It is considered more difficult compared to E3, because the SWS has to be repartitioned between the two cores, which can lead to lots of difficult wakes. Compared to Bimaxion, it is similar in difficulty, with both being incredibly difficult, reporting only a few successes over the years in non-short sleepers.
With SWS deprivation being present throughout most of the adaptation, oversleeping can occur in any of the five sleep blocks. Even when the wake gap between each sleep seems to be short, staying awake can still be exceedingly difficult, especially at night.
The extended variant is expected to be easier, and may be a viable route to transition to Ducamayl, though no one has attempted doing so thus far.
Lifestyle Considerations
In terms of lifestyle considerations, DC3 is similar to the other schedules in the group. Because of a lot of sleep blocks each day, it becomes difficult to schedule food and activities in to the gaps. The schedule includes at least two daytime naps, which is difficult to manage for many.
With only 4 hours of sleep, intense exercising may not be suitable as the greatly reduced total sleep may impair recovery processes. Sickness and injury, which can result in excessive sleep, may also break the patterns of the schedule even after adapting.
It is also unlikely DC3 will be flexible after adaptation due to its low total sleep. With the distribution of sleeps across a lot of usually socially busy hours, DC3 is more of a short-term polyphasic schedule with a lot of naps for more opportunities of vivid dreaming. Being overshadowed by its counterparts E3 and even E3-extended, DC3 generally has limited viability for any long-term consideration, with all aspects considered.
Variants
Since there are only few adaptations to DC3, there are only few respective scheduling variants should one decide on DC3 for the high frequency of sleep, which can boost alertness around the clock with the dense number of naps.
Extended variant
This extended version has a long core sleeps and boosts the total sleep to 7h each day. It has recorded one successful adaptation from the Discord community. There is only a 90 m wake gap in between 2 cores, but because the sleeper was a well-entrained segmented sleeper, the short wake gap posed no problems during adaptation. This small wake gap is also dedicated to praying, which does not require several hours staying awake like on other Dual Core schedules. Despite the inconvenient scheduling, it is possible to adapt to this variant with an appropriate lifestyle and certain personal motivations.
Version 2 has a more realistic setup than the first version, with a reasonable amount of total sleep and can handle the sleep onset issues better during adaptation than the first version. Over the years it has reported one success or so, mostly because of the intrusiveness of the sleep blocks. If scheduling is possible, the wake gap between 2 cores can be used for more activities and the distribution of sleeps can make for a comfortable adaptation, where skipping a nap on this variant during adaptation should not do as much damage as on the standard version. However, it is recommended that beginners should pursue E3-extended instead, with the same amount of sleep, much higher success rate and more beneficial scheduling.
