Leif Weaver, the first polyphasic sleeper with a successful adaptation to Triphasic, remained on the schedule for several months. This schedule was known to be equidistantly scheduled, with a 6.5h wake gap between each core sleep. Because of the structure, Triphasic can be considered a more extreme Segmented schedule, with a long siesta. Despite the origin of the schedule, equidistant sleep is not required, although '''no more than 8h''' wake gap between any core sleep is recommended. For the daytime core and with the recorded successes in Triphasic (except Triphasic-extended), it is possible to stay awake for up to '''9 hours''' from the daytime core to the core around SWS peak hours, while the wake gap between the 2 other cores around night hours tends to be smaller.

Because of the major difficulty posed by the SWS core during adaptation, this extended version allows more room for SWS in the first core, with a higher chance to avoid many SWS wakes during adaptation. This also bumps the total sleep time to 6h, which is considered a beginner-friendly sleep total. Alongside a much easier adaptation, the wake gap from the REM core to the afternoon core can be expanded all the way to ~11h wake gap (1 reported success). This versatility greatly boosts the viability of Triphasic-extended or schedules with a daytime core. A few polyphasic sleepers have been able to adapt to a Triphasic-extended variant with a 9-10h wake gap from morning to afternoon. The ability to schedule this distribution of sleep aids in daily scheduling, in which the daytime core can be moved to ~'''4 or 5 PM'''. With an overall easier adaptation than regular Triphasic, the night time hours between 2 nocturnal cores can be utilized for various activities without having to sacrifice all productivity when adapting. Another bonus from Triphasic-extended is that the '''first core can begin at late evening hours''', around 11 or 11:30 PM without too much hassle, thanks to the increased total sleep. The core extension also suits individuals with somewhat high sleep requirements, while an adaptation to the regular Triphasic can become unsustainable.

Alternatively, it may be possible to '''extend the REM core to 3h''' instead of the SWS core in the evening, which may be beneficial for social hours in the evening or less sleep in the early evening hours. However, it has no known official successes to date. Although it is worth noting that a sleeper with low SWS needs and high REM needs may benefit from this Triphasic-extended variant.
