Translations:Scheduling overview/16/zh-hant

Here is a basic classifcation of schedules by their difficulty level, assuming a typical sleeper with 8h monophasic sleep and normal levels of SWS and REM:

難度	時程示例	TST範圍	睡眠削減量	備注
簡單	二相X, E1-延長, Siesta-延長, 分割-延長	7-8小時	<1小時	Recommended for beginners or those needing significant flexibility.
中等	E1, E2, E3-延長, Siesta, DC1, Triphasic-延長, 分割, DC1-延長	5-6小時	1-2小時	Require a significant adaptation process, but can be quite flexible after adapting.
困難	E3, DC2	4-5小時	2-3小時	Require harsh adaptations and are not particularly flexible for most people.
頗爲困難	DC3, Bimaxion, 三相	4-5小時	2-3小時	Considered harder than the "Hard" ones because they do not contain a longer core during SWS peak hours.
非常困難	E4, E3-縮短, Uberman, Dymaxion	<4小時	>4小時	Not considered possible for most people.
