MonoCore-1

MonoCore 1 is a biphasic schedule in the reducing Everyman (here referred to as MonoCore for consistency with other schedules) lineup created by Puredoxyk in Ubersleep (see naps). It removes one cycle of sleep from the default 7.5h core and replaces it with a nap. As a biphasic schedule, it is one of the best for beginners.

Mechanism

As described in Naps, the nap is meant to largely replace one of the core cycles. In practice though, it often does not contain vitals, simply restoring some anysleep-pressure.

Difficulty

As a biphasic schedule with TST above 6h, M1 is quite easy to adapt to. While not non-reducing, it is a very low reduction and no repartition of vitals into the nap is necessary for most. This means the adaptation only relies on reducing light-sleep percentage, instead of several mechanics which would each provide a point of failure.

*However:

Some people also have more difficulty than with more reducing monocore schedules like M3ext or M2; due to the low amount of sleep debt accumulation in M1, the required threshold for stage-3, and thereby adaptation, might never be reached, leaving one stuck in stage-2. DualCore schedules, especially DC0 are a great alternative if this happens.

In people with RSR, M1 often turns into M0-Shortened or MX-Shortened.

Scheduling headroom

Scheduling headroom does not refer to flexing. Once chosen, Consistency within the schedule remains a requirement. All schedules can be rotated arbitrarily with sufficient dark-period and light period.

The nap can be moved around by at least 2h in scheduling without causing too much sleep pressure buildup. Once chosen, sticking to the time remains important.

Adaptation

Adaptation to M1 from Mono is best done cold turkey - just jump in, don't skip a night, and don't do any kind of gradual change.

Extension

M1-Extended is largely only useful if you have increased sleep requirements, otherwise, MX (aka. Biphasic-X) is far preferable.
