This option is considered standard. It usually has 3h20m first core and 1h40m second core, theoretically making sleep cycles a bit longer (close to 100m). In fact, according to EEG readings of some community members, sometimes cycle lenght might be unchanged and shorter, so there is more LNREM inserted in the end of cores.<ref>[https://www.imgurupload.com/uploads/20201117/13e019f96f652f0ec610a4fc9f1827c99510151b.jpg Zeo reading of a shorter core]</ref><ref>[https://www.imgurupload.com/uploads/20201117/5b634c74a7ea495e7158299c35f303c47375b86c.jpg longer core]</ref>

This variation is rarely used and has a lower success rate since cores contain less light sleep/REM. It is considered more difficult than the standard one, and usually fits people with lower natural monophasic sleep baseline, about 6-7 hours or less.

This variation has standard cores' length, 3h + 1.5h. It is rarely used and has a lower success rate since cores contain less light sleep/REM. It is considered more difficult than the standard one, and usually fits people with lower natural monophasic sleep baseline, about 6-7 hours or less.

The easiest and a popular option, which has several variations. Usually 3h+3h or 4.5h+1.5h core versions are used, but other options are also possible (e.g. 1.5h+4.5h or 3.5h+3.5h). It usually has 4 cycles instead of 3 (5 or more is also possible, but almost never is used). This variation fits adolescents or those with higher sleep requirements.
