'''DC2-extended''' simply extends the second core sleep by a full cycle, making it 3h total. This variant shares the same total sleep as E2-extended, with the exception of having 2 core sleeps. People with high sleep requirements (especially in both REM and SWS) can make use of the sleep frequency and the assistance from naps to meet the necessary vital sleep requirements. The only advantage of this version is that the first core can be delayed to the last hours of SWS peak - meaning it is possible to schedule this core at 11 PM or later. However, while looking realistic on paper, DC2-extended has never really reported any successes. It is also outclassed by '''E2-extended''', which is more convenient in scheduling, more success and an allegedly easier adaptation. While it is possible to schedule the first core to be 4.5h long and the second core to be 1.5h long (for more SWS recovery from intense exercising or high SWS requirement), DC2-extended is also shadowed by '''DC1-extended''', which has the same total sleep for both cores combined while only requiring 1 daytime nap (more comfortable to keep up long-term).

=== TC1 structure ===
This is an experimental variant, proposed by [[User:Sekvanto|Sekvanto]]. Both cores have the same length of 2 hours. Three blocks of sleep are placed during the night hours: both cores and one of the naps. The second nap is placed midday. Such schedule resembles the structure of [[TC1]], replacing one of the cores with a nap and extending the remaining cores. This variant has less naps during the daytime, which potentially makes it more convenient socially for some. An early core may be an issue, on the other hand. Another benefit includes a dawn nap, which may increase dream recall.
It should be noted that 2h [[cores]] are usually considered a bad choice, since they are a bit longer than an average sleep cycle, which makes SWS wakes more possible. This schedule overall isn't popular and had only a couple of successful adaptations. However, 2h cores work for some, supposedly either by having extended sleep cycles or by getting more light sleep in the end of the cores.
