For these reasons, DC3 is not commonly attempted compared to schedules with similar amounts of sleep, like E3.

	[[File:DC3-extended.png\|thumb\|~~Version 1 of~~ DC3-extended\|alt=]]		[[File:DC3-extended 2.png\|thumb\|DC3-extended\|alt=]]
	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.

This variant contains an extended first core to ease the SWS deprivation. Over the years it has seen few attempts and only one recorded success. Not much is known about this schedule. It is expected to resemble DC1 and DC2, but with more frequent naps.

	~~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.

[[File:DC3-extended.png\|thumb\|DC3 with both cores extended\|alt=]]
			One [[Polyphasic Sleep Discord\|Discord]] user has adapted to a variant with both cores extended to 3 hours, with the core gap reducing to only 90 minutes. This does not pose issues as the user is an experienced polyphasic sleeper who have been adapted to a similar [[Segmented]] schedule before, and has good napping skills.

	~~Polyphasic sleepers~~ can start ~~an adaptation~~ to [[TC2]] ~~and then slowly transition to DC3 [[(rhythmic preservation\|('''rhythmic preservation''']]~~, ~~using~~ the ~~same number of sleep blocks on each schedule and change a~~ core ~~into~~ a nap), ~~although this path will take a very long time to achieve for both steps~~. Alternatively, ~~a '''[[gradual adaptation]]'''~~ from [[DC2]] or [[DC1]] also ~~looks viable~~, but ~~so far there are~~ no ~~known~~ successes ~~with this method~~. Starting the ~~schedule '''~~[[cold turkey]]~~''' (from [[monophasic]])~~ has reported at least one successful adaptation ~~(in the case of a [[sleep mutant]])~~. Regardless of the adaptation pathways, sleepers would ~~eventually~~ need to go through the ~~intensified~~ [[repartitioning]] of vital sleep stages to be able to ~~finally~~ adapt to ~~the regular DC3 setup~~.		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 ==		== Difficulty ==
	DC3 ~~is also one of the 3 schedules whose original design would provide only '''~~4 hours of sleep~~''' each day. The other 2 schedules in the same category of minimum sleep threshold for adaptability are [[E3]] and [[Bimaxion]]~~, ~~an easier equivalent of [[Dymaxion]]~~. It is ~~generally agreed on that DC3 is a lot harder than~~ E3, ~~due~~ to the ~~number~~ of ~~rare adaptations and how many days each polyphasic adapter lasts on this schedule before forfeiting their attempt~~. Compared to Bimaxion, it ~~may be equal~~ in ~~terms of~~ difficulty, ~~which is already formidable for any polyphasic beginners barring sleep mutants~~ with a ~~low monophasic baseline. One niche of~~ the ~~cold turkey adaptation is that~~ non-nappers will be able to learn to nap effectively faster than on schedules with fewer naps or higher amount of sleep; this is owing to the immense sleep pressure from the schedule that builds up swiftly.		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]].

	Nonetheless, because the longest sleep block on the schedule is only 90 minutes long, DC3 is one of the most difficult polyphasic schedules to adapt to. Even though it has a high frequency of sleep (5 sleeps per day), waking up after only 90 minutes of sleep around graveyard hours makes SWS and/or intense REM wakes very frequent during adaptation. With SWS deprivation ~~symptoms~~ being present ~~until an equilibrium and healthy amount~~ of ~~SWS is obtained~~, oversleeping can occur in any sleep blocks~~, especially the core sleeps~~. Even when the wake gap between each sleep seems to be short, staying awake ~~during graveyard hours during adaptation is going to~~ be ~~a major task~~, ~~when sleep inertia from the repartitioning cores can prove to be overwhelming~~.		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.

	~~However, '''DC3-~~extended~~'''~~, ~~despite its troublesome scheduling of sleeps~~, has reported one success in 2020, effectively suggesting that the concepts and design of DC3 are still hospitable for adaptation. The extension of a core sleep on this version facilitates a much more challenging would-be adaptation on the regular DC3 version.		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==		==Lifestyle Considerations==
	~~Because DC3 possesses all the features~~ of ~~Dual Core sleep~~, ~~the lifestyles that apply~~ to the ~~previous DC~~ schedules ~~can somewhat apply to DC3. The wake gap at night can be dedicated to religious activities (e.g, praying), studying or planning depending on how long it is~~. Because of a lot of sleep blocks each day, it ~~is necessary~~ to schedule food and ~~other commitments carefully before attempting this schedule~~. ~~Only '''flexible, work-from-home occupations''' can benefit from this~~ schedule ~~- working~~ at ~~one's own pace in a familiar environment~~ is more relaxing and less demanding than under constant supervision of a boss or a high-ranking member at the office; the amount of [[wikipedia:Sleep_deprivation\|sleep deprivation]] can be insurmountable and can damage a lot of productivity hours when adapting in a more stressful and rigorous environment (e.g, jobs that require constant vigilance, high focus or sharp mental concentration around the clock, having to ~~nap at a noisy workplace or in public, or evening events)~~. ~~In addition, with~~ only 4 hours of sleep, intense exercising may not be suitable as the recovery ~~process may not suffice with increased SWS requirements~~. Sickness and injury, which can result in excessive sleep, may also break the patterns of the schedule even ~~with the adapted state~~.		In terms of lifestyle considerations, DC3 is similar to the other schedules in the group.

			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.

	== Mechanism ==		== Mechanism ==
	~~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 ~~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~~.		{{further\|Dual core#Mechanism}}
			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.

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.

	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.

	== Adaptation ~~Methods~~==		== Adaptation==
	Polyphasic sleepers can start an adaptation to [[TC2]] and then slowly transition to DC3 [[(rhythmic preservation\|('''rhythmic preservation''']], using the same number of sleep blocks on each schedule and change a core into a nap), although this path will take a very long time to achieve for both steps. Alternatively, a '''[[gradual adaptation]]''' from [[DC2]] or [[DC1]] also looks viable, but so far there are no known successes with this method. Starting the schedule '''[[cold turkey]]''' (from monophasic) has reported at least one successful adaptation (in the case of a sleep mutant). Regardless of the adaptation pathways, sleepers would eventually need to go through the intensified repartitioning of vital sleep stages to be able to finally adapt to the regular DC3 setup.

	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 ~~90m~~ 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.

	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.
