Both core sleeps are scheduled to be 3.5 hours by default because the sleep cycles are known to lengthen to about 105 minutes from the approximately 90-minute cycles on monophasic sleep. This would also explain the viability of the schedule despite having fewer cycles.

The wake gap between each core (known as "core gap") should at least 90 minutes, with a longer gap recommended (~2.5-3 hours) for non-natural Segmented sleepers. The reason for this is to prevent the cores from becoming interrupted sleep. Interupted sleep is when there is a only a brief period of awakening before going back to sleep which disrupts the sleep cycle and drastically reduces sleep quality.

The wake gap between each core (known as "core gap") should at least 90 minutes, with a longer gap recommended (~2.5-3 hours) for non-natural Segmented sleepers. The reason for this is to prevent the cores from becoming [[interrupted sleep]] and to prevent the difficulties with falling asleep or being productive enough.  

 

Staying awake for at least ~90m will usually prevent this, so that the second core starts in a new sleep cycle. A core gap that is too short is unlikely to be productive time, and may also result in the sleeper having a difficult time falling asleep due to insufficient sleep pressure. The original default recommendation was a 2-hour gap, but has since been changed to 3 hours as some were unable to fully adapt to the 2-hour gap version.
