Using slightly shortened cores would be more difficult, as it has less total sleep time. Repartitioning of sleep stages will need to be more intense than on the standard version. This may be suitable for those with slightly lower monophasic needs (~7h). It is unknown how flexible the variant would be after adapting, since there are no records of its flexibility, and the successful adaptees did not maintain the schedule long enough.
