A 60m sleep block is usually discouraged for attempting under most, if not all, polyphasic patterns. However, under '''non-reducing condition''', it can be natural to wake up after 60m rather than a full 90m core. 60m sleeps have been anecdotally researched and tried by a couple of polyphasic sleepers over the years who often naturally fall back to this seemingly "odd" sleep duration. The reason is that the 60m sleep duration provides mostly SWS and the sleeper would likely wake up during the transitional light sleep stage, before the usual REM sleep block would enter. Under non-repartitioned sleep, all sleep cycles follow the regular order, in which NREM1 initiates the cycle, followed by NREM2 (starting to actually fall asleep), SWS (deep sleep, unaware of the surrounding), NREM2 (transition stage) and finally REM sleep. The body at this point has completed the required amount of vital sleep in the day and naturally wakes up, without compressing the core sleeps. However, outside of non-reducing condition, a 60m sleep block should not be scheduled from the start.

Another great boon of non-reducing version is that sleepers do not have to be confined to a specific duration of daytime core length, as long as it's no shorter than ~50m (to differentiate with E1). and can be as long as ~2h. Thus, non-reducing Siesta has a lot of flexibility in scheduling, and heavily favors natural wakes (e.g, 60m daytime core one day, and ~80-90m core the next day). The goal is to ensure there is no sleep reduction from monophasic baseline to get as much productivity during the day as possible (for events or circumstances that require sharp decision-making and/or focus like examinations).

It is also not a requirement to sleep at the exact same hours everyday for both sleeps even when adapting (though consistency of sleep times is great).
