== Dual core schedules ==
== Alternative mechanism ==
{{Alternative Hypothesis}}
It was noticed by some polyphasic community members that a longer core length, which is not a multiple of 1.5h, did not lead to the cycle lengthening on dual core schedules in some cases. This is mostly applicable to the standard Segmented and DC1 schedules.
 
=== Core 1 ===
The first core on the standard Segmented is 3.5 hours, and 3.3 hours on DC1. The additional 20-30 minutes often are added to [[cores]] for getting more [[wikipedia:Non-rapid_eye_movement_sleep|NREM2]] or [[wikipedia:Rapid_eye_movement_sleep|REM]] sleep. In this case, sometimes the core has a normal structure with the standard sleep cycles length. Some additional light sleep is inserted after the second core, which makes waking up and staying awake easier.
 
=== Core 2 ===
According to the [[EEG]] readings of some community members, the second core on dual core schedules often starts with [[SOREM]], following by a regular non-lengthened sleep cycle. This is also a possible reason why Segmented sleep is a viable schedule despite having fewer cycles. In fact, it might have a regular number of the REM episodes, considering SOREM in the second core is the fifth one.

Segmented and siesta, along with [[E1|Everyman 1]] (a single core sleep schedule), tend to have high success rates within the polyphasic community.<ref>[https://youtu.be/BA24s8KwBi0 Polyphasic Survey Results and Analysis (2018)]</ref>

[[Bimaxion]] is a strict schedule that combines elements of DC2 and [[Dymaxion]] (an experimental nap-only schedule), designed as a transitional schedule with Dymaxion in mind. The total sleep time is 4h.
