DC4 is vastly inferior to DC3, and the transition to Uberman can take several months. So far, it remains a hypothetical polyphasic schedule that has not been far from being fully tested, and notably no one has adapted to Uberman from this schedule, either.  &lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

It can be used as a less extreme form of Naptation thanks to 2 core sleeps. Sleepers can choose to start this schedule temporarily as a way to learn how to learn the short naps, recover on monophasic afterwards, and start a polyphasic attempt anew, including Uberman if desired. DC4 may also act as a fallback schedule if Uberman or E5 happens to fail, but no one has pulled this off so far. With everything being &#039;&#039;&#039;mostly hypothetical&#039;&#039;&#039;, there is little to no use in attempting this schedule.
