[[DC4|Dual core 4]], usually denoted as DC4, has two short cores at night and four naps. The total sleep time of DC4 is generally 4h20m. This schedule is often used as a means for gradual adaptation to Uberman, but so far no successful attempts has been known with this approach.

[[DUCAMAYL]], an acronym for "dual core as much as you like" is a variant of SPAMAYL that includes two core sleeps, generally at dusk and dawn. The idea is to adapt to a general dual core sleep schedule, one in which the individual learns the flexibility to move around start & end times of their cores & nap(s). The total sleep varies broadly, though is generally 5h30m to 7h.
