The name DUCamayl stands for “Dual Core As Much As You Like”. It is one of the 4 “-AMAYL<nowiki>''</nowiki> flexible polyphasic schedules, the other ones being [[Spamayl]], [[Sevamayl]], and [[Camayl]].

Until recently, there has only been one anecdotal success from sleeper [[Aethermind|Aethermind's]] father, who has been unintentionally maintaining the schedule for more than 20 years without signs of ill health. His schedule consists of 2 somewhat flexible core sleeps and between 1 and 2 naps in the day.

First created and roughly drafted in 2017 in the [[Polyphasic sleep discord|Discord]], it was proposed as a flexible Dual Core counterpart to Sevamayl, a flexible [[Everyman]] schedule. In 2020, there have been two more recorded successful adaptations to DUCamayl, which are by [[GeneralNguyen]] and [[UncertainBeing]].

The mechanism of DUCamayl is believed to resemble that of Sevamayl, with two shorter cores in place of the long Everyman core.

As with all other Dual core schedules, the first core sleep provides mostly [[wikipedia:Slow-wave_sleep|SWS]] while the second core favors [[wikipedia:Rapid_eye_movement_sleep|REM]] sleep, with the nap(s) providing some REM and alertness boosts. Naps can be taken when alertness drops.

After adapting to a rigid base Dual core schedule, the body gets used to the new sleep pattern, which involves 2 core sleeps and a number of naps, as well as the reduced total sleep. Then, the sleeper gradually adapts to [[flexing]], allowing naps to be moved, added, or removed. Because of 2 core sleeps covering much of the night and morning in which the alertness is the lowest, DUCamayl tends to have fewer [[naps]] than Sevamayl.

==Scheduling==

There has been some attempts at adapting to the schedule cold turkey, but they have virtually all failed. As with Sevamayl, first adapting to a strict Dual core base schedule seems to be necessary. The possible base schedules to start from include DC1, DC2, DC2-extended, as well as DC3-extended.

The process of adapting to DUCamayl from the rigid base schedule is similar to that of Sevamayl. First, one can start with [[flexing]] the naps slightly, such as by 30 minutes forward or back. Then, the cores can also be optionally flexed slightly. Over time, one can gradually increase the flexiblility windows of the sleeps. Finally, naps can be added or removed according to the level of tiredness one experiences in a given day.

It is important to do this gradually, however, as flexing all the sleeps right away can destabilise the adaptation. One or both cores of DUCamayl can remain fixed, instead focusing on the flexibility of naps for convenience in daily scheduling.

During and after the adaptation, some naps as well as cores may shorten. The best strategy is to get up as long as a good amount of sleep has already been gained since the schedule allows for extra naps later if you get tired.

==Lifestyle considerations==

Like other “-AMAYL” schedules, people with irregular life schedules greatly benefits from DUCamayl. Similar to Sevamayl, DUCamayl is not very suitable for those on strict work schedules, since the ability to flex naps can be gradually lost if not regularly used. Compared to Sevamayl, DUCamayl generally requires fewer naps in the day, but involves a second core that may limit early morning activities.

Under emergency or social events, both cores sleeps can be delayed to allow more time awake in the evening. Alternatively, the first core may be skipped, and the second core may be extended by one cycle, though this would incur more sleep debt and be more destabilising. The [[dark period]] should change as little as possible to ensure a stable circadian rhythm. As a dual core schedule, however, it is inherently less accommodating to [[Circadian management#Late cores|late cores]], and those who needs to do this frequently are recommended to choose Sevamayl instead.

==Variants==

==Variants==

As with Sevamayl, DUCamayl can be derived from a range of base schedules. For average sleepers, at least 4-5 hours of time in cores is required to make the sleeps flexible, which would be around 5-6 hours of sleep in total. For this variant, DC2 and DC2-extended can be used as base schedules. The combinations of core lengths need not be standard; one of the two recorded attempts utilised a DC2 variant with two 2.5-hour cores.

People with reduced sleep needs may be able to transition to DUCamayl from either DC3 or Bimaxion, with about 3 hours of sleep in cores. One Discord user with reduced sleep needs successfully transitioned to this schedule from Bimaxion. However, these schedules are known to be exceedingly difficult to adapt to for average sleepers, and is unlikely to ever be flexible for them.

Alternatively, it is also possible to use a base schedule with 6 hours of sleep in cores. This variant would require fewer naps, with possibly some days without any nap at all, though it is debatable whether a Dual core schedule without naps on some days would qualify as DUCamayl.

The characteristics of the base schedules still apply on DUCamayl. For example, variants with more total sleep time allows for more flexibility and is more tolerant to later cores, and those with longer first cores will provide SWS more effectively.
