From Polyphasic Sleep Wiki
The most common core length of Sevamayl is often scheduled to be 4.5 hours. This may naturally decrease to about 4 hours with cycle compression after a long time. Some, especially those with lower sleep needs, may be able to adapt to a 3.5-hour core, but most sleepers cannot gain much flexibility from the shorter core. On the other hand, a 6-hour core is also possible as a less extreme form of Sevamayl, though less popular. The dark period should stay consistent on a day-to-day basis, even if the nap/core timings change, to ensure a stable circadian rhythm.
