Their mechanism is mostly not the same, and only high total sleep time is a similar feature. Less reduction is possible because of the [[wake time reduction]] mechanism, as biphasic schedules have only two blocks of sleep, which is not enough to sleep much less than on [[monophasic]] sleep. The maximum possible reduction is usually around 1-3 hours. All the biphasic schedules also belong other polyphasic schedules categories. | ||

[[BiphasicX]] is a flexible [[non-reducing]] biphasic sleep schedule, which consists of two blocks of sleep of any length. This schedule can combine all the other biphasic schedules. Usually it takes form of a non-reducing E1 / Siesta, having a long core at night and a short nap / core midday. However, a Segmented-oriented variant is also possible. | |||
This schedule has a potential for those, who needs a great sleep flexibility since the very beginning, as the adaptation is usually very mild and the absence of sleep reduction makes it possible to have a wider flex range. | |||
