The wake gap between the core and the first nap should be the shortest, while the gap before core can be the longest because of higher alertness during late afternoon hours. The first nap can be between 3.5-5h after the core, and the last nap can have an 8-9h wake gap until the core.

The 4.5h core allows all [[wikipedia:SWS|SWS]] needs to be met even during adaptation, sincemonophasic sleepers typically gain all the required SWS by the middle of the night, after their 3rd sleep cycle. The ideal core placement is around around midnight, for a good balance of REM and SWS pressures. It is recommended for the first nap to be placed the middle of the [[wikipedia:Rapid_eye_movement_sleep|REM]] peak of 6-9AM, allowing high quality REM sleep for the nap. The second nap on E2 may only contain light sleep rather than REM sleep, especially if this nap is late into the afternoon (e.g, 4 PM onward).
