The idea behind TC2 is not to cram all three core sleeps into the night like on TC1, or having all cores somewhat equidistant like on Triphasic. Since the sleep frequency of TC2 is the highest among the Tri Core family, which overall has a very low number of naps needed, all sleeps, including the cores, are spread out, with 2 cores being focused at night (and potentially take on the feature of [[Dual core|Dual Core sleep]], where the midnight core favors [[SWS]], while the core around sunrise hours favors [[REM]] sleep). The third core, located at late afternoon hours, coincides with the timing after usual hours of school and work as a way to give a long recovery after a long day.

The third core, located at late afternoon hours, coincides with the timing after usual hours of school and work as a way to give a long recovery after a long day.  

The daytime naps serve to provide a high frequency of sleep and bolster alertness levels. Because of the high frequency of sleeps, staying awake between each sleep on TC2 may not be as difficult as on Triphasic and TC1. Most notably, compared to the original Triphasic sleep, '''TC1 and TC2 give more total sleep''', which only happens in the Tri Core schedule group. This is because the 90 m cores are already at the lowest number of sleep cycles, and the total sleep increases because of the addition of nap(s).

Because of a generally bigger wake gap between the cores, it may be easier to fall asleep in the 2 cores around [[graveyard hours]] (~midnight to 8 AM), which can lower the chance of [[oversleeping]] with subsequent naps and another core in the late afternoon. This late afternoon core likely behaves the same as the daytime core on Triphasic, giving mixed SWS and REM.

Aside from this standard variant, '''no other variants''' of TC2 have proved to work thus far.  

Aside from this standard variant, '''no other variants''' of TC2 have proved to work thus far. Extending any of the core sleeps by 90 m proves to be more of a nuisance to schedule 5 sleeps, and it is highly ill-advised to attempt any extended versions. Because TC2 looks very redundant, it is a better approach to attempt any of the more convenient schedules as mentioned above.
