Dual Core 1, or DC1, is a schedule which logically follows Segmented sleep, and it is the first Dual Core schedule, with the reduction of some sleep from the second core of Segmented and the addition of one daytime nap to compensate for the reduced amount of REM in the second core. This allows for some sleep reduction on the schedule, and polyphasic sleepers will now officially be able to learn to nap, as Segmented sleep does not have any naps.
DC1 is also considered an ideal polyphasic schedule to attempt, given his total sleep, which ranges from ~5.3-6.3h and is very friendly for beginners.

Adaptation
Alternate variations
Extended sleep cycles
This option is considered standard. It usually has 3h20m first core and 1h40m second core, theoretically making sleep cycles a bit longer (close to 100m). In fact, according to EEG readings of some community members, sometimes cycle lenght might be unchanged and shorter, so there is more LNREM inserted in the end of cores.[1][2]
Standard sleep cycles
This variation is rarely used and has a lower success rate since cores contain less light sleep/REM. It is considered more difficult than the standard one, and usually fits people with lower natural monophasic sleep baseline, about 6-7 hours or less.
Equal core length
Both cores are of the same length. This variation is viable, but rare. It is also considered more difficult than the standard one, since requires sleep cycle compression.
Swapped cores
In this variation the first core is swapped with the second one. The difficulty is also higher, because of the possible SWS wakes and the need for SWS splitting, which is easier for either experienced polyphasic sleepers or those with lower SWS sleep requirements.
Extended
The easiest and a popular option, which has several variations. Usually 3h+3h or 4.5h+1.5h core versions are used, but other options are also possible (e.g. 1.5h+4.5h or 3.5h+3.5h). It usually has 4 cycles instead of 3 (5 or more is also possible, but almost never is used). This variation fits adolescents or those with higher sleep requirements.
Shortened
This option has only 2 sleep cycles, for example 1.5h+1.5h or 2h+2h. Is much harder and recommended only for those with lower sleep needs, 6h mono or less. It allows for much less LNREM/REM.
