From Polyphasic Sleep Wiki
Everyman 1, or E1, is part Everyman and part Biphasic, it trades one cycle from monophasic for a single nap in the day. Because of the sleep cut from the core, sleep deprivation will gradually build up, and enable sleepers to eventually fall asleep in the nap. This process is likely a lot easier than learning to nap on a non-reduced Biphasic schedule (i.e., Biphasic-X), because there is more sleep pressure generated from a shortened nocturnal core sleep.
