There are, however, a lot of hefty benefits from this type of variant. For one, '''social time in the evening''' is secured, because sleep time is not as early as the standard version. For another, the '''wake gap between 2 cores can be smaller''' than the original version, because of a potentially higher SWS pressure that will be resolved in the second core sleep. This setup would also benefit those who can wake up at later hours in the evening with a shifted work schedule to late morning or later. A somewhat short sleeper would even benefit from this variant more - not only is sleep time reduced somewhat, but all the access to evening events like other monophasic individuals and an uninterrupted flow of daytime commitments, without needing any naps. Adaptation to this variant is expected to be very difficult, which is one important note to bear in mind.

The slight difference between Segmented-extended and non-reducing Segmented is that the former can still contribute to some amount of sleep reduction (e.g, 9h monophasic sleeper), while the latter does not reduce any sleep (e.g, 4.5-4.5 core combo for 9h sleeper). Either variants, however, only report some success over the years. The '''non-reducing''' variant has achieved a lot of success since the preindustrial era, which brings up the point that segmented sleep can be a natural sleep pattern for humans. Nowadays, with the advent of blue light and certain difficulties in managing the schedule alongside social time and hassling evening hours, it is deemed a lot harder to adapt to either variant. Another downside of both variants is that the longer core sleeps plus the wake gap between 2 cores makes the second core end later than usual. This can then clash with morning commitments if one has to wake up earlier than expected.

In spite of all the powerful advantages, Segmented seems at a disadvantage compared to other biphasic schedules when attempted by underage individuals, mostly those who are not natural Segmented sleepers. It may be possible that these individuals are better off with a long, continuous core sleep rather than segmented core sleeps, which can be a reason for quite a few incomplete adaptations.
