From Polyphasic Sleep Wiki
DC1 is a schedule of moderate difficulty. For naturally segmented sleepers, it is likely to be easier and more natural than E2. However, for others, E2 would be much easier, as it does not require SWS to be repartitioned. DC1 is known to be less flexible compared to E2, and as with all other Dual core schedules, it is much less tolerant to late cores.
