Compared to the standard, this variant has gap sizes that more closely follow circadian sleep pressure. There is a slightly longer wake gap between the sunrise nap and the noon nap, which allows for more wake time in the morning to maintain an uninterrupted work time. The last nap is moved to early evening, for convenience. Compared to E4, the naps are still close together, as each nap sustains wakefulness less than on other schedules due to the shortened core. It is advised to avoid wake gaps larger than ~5 hours ( other than last gap) on regular E4.
