So far all successful Dymaxion attempts have been achieved through this method. A few days after starting, intense [[wikipedia:Sleep_deprivation|sleep deprivation]] will become ensue, which needs to be overcome.

As with Uberman, it is strongly recommended to have human supervision to avoid oversleeps. Any oversleeps will greatly set back the adaptation process, effectively resetting the whole nap architecture built up to that point.

Dymaxion shares a lot of similarities to Uberman, including extreme difficulty and very low flexibility. Like with Uberman all of the [[wikipedia:Slow-wave_sleep|SWS]] and [[wikipedia:Rapid_eye_movement_sleep|REM]] must come from naps on this schedule, so the amount of SWS and REM in proportion to [[wikipedia:Non-rapid_eye_movement_sleep|light sleep]] is very high. Dymaxion still tends to be less popular than Uberman.

Difficulty-wise Dymaxion is likely harder than Uberman. Because of the larger gap between naps (5h30m compared to 3h40m), sustaining wakefulness will be more difficult than on Uberman. Since SWS usually begins by the 25-minute mark, naps will contain SWS right from the start, which may cause SWS wakes as soon early on. However, this matters little overall, as overcoming the SWS rebound is necessary in order to adapt to either schedule.

SWS wakes in naps may cause difficulty hearing alarms, which may directly cause oversleeps, even without consciously deciding to. It is also much more tempting to go back to sleep after an SWS wake, even if you do wake up. Naps ending in SWS are less likely to produce dream recall, which may be unsatisfying to some.

There has been one single-case study<ref name="study"/> on Dymaxion-6 conducted by [[wikipedia:Claudio_Stampi|Claudio Stampi]]. Francesco Jost was the volunteer for the study. He participated in another study prior to this one, which inspired this idea. Jost is a normal monophasic sleeper (8h baseline), in good health conditions and did not have any polyphasic sleeping experience before these two attempts. It is possible that he has average REM and SWS baselines.

The study lasted for 48 days, of which 34 days were used to adapt to the schedule, discounting some transition days in which he gradually reduced sleep. On day 34 and after the end of the experiment, he was allowed to sleep ad lib, that is, as much as desired.
