However, because of a high total sleep, it may take a long time to finally be able to fall asleep in the nap compared to standard E1. The adaptation to E1-extended may last just as long as the regular version, but with a much milder adaptation and possibly silent stage 3, with no signs of severe sleep deprivation symptoms or crippled productivity as seen on other more reducing schedules that has been observed in successful adaptations. Picking this variant as a result may give the benefit of potentially maximizing daily performances (physical and cognitive) at work and/or school even when adapting.
