Changes

With all the downsides, DC4's use is mostly to '''learn to nap''' with the high number of naps per day. 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 '''mostly hypothetical''', there is little to no use in attempting this schedule. DC3 would be the more preferable choice.
