It is worth noting that the failure to nap after several weeks (despite adhering to the schedule by the minute and all methods have been used to facilitate napping) may be attributed to the BRAC in scheduling. Since sleep pressure on E1 is generally lower than on other schedules with less total sleep, ideal nap times in which the body feel drowsiness are only at a few certain spots in the day. This can cause the nap to work poorly because the body only tired either before or after nap. The problem would be resolved if the nap is moved to those spots.
