Translations:Sevamayl/7/en

The most common intermediate adaptation step is E3-extended, but E2-extended is also possible for a 6-hour core Sevamayl. E4-extended should work for people with sleep requirements on the lower side, but it is unclear how flexible a mere 3.5 hour long core will be on an adapted Sevamayl. There are only reports of a few successful E3-flex sleepers where one or two naps were a bit flexible, but otherwise required strict timing. A 3 hour core will likely not work. When comparing the raw nap flexibility of 3 hour versus 3.5 hour core E3, the difference is massive in that the 3-hour core schedules have nearly no flexibility at all.
