From Polyphasic Sleep Wiki
E2 removes two cycles from monophasic, and adds two nap, each containing similar amounts of REM to the removed cycles. The core sleep of E2 has 3 full cycles of 90m each. By default, the first nap is scheduled at around sunrise, and another nap is scheduled in early afternoon. Two naps break the long day into shorter wake gaps, which helps the body sustain itself on reduced total sleep.
