E2 with 5h core

This variant is still called E2 (not extended), as it is a minor extension. The reasoning behind this is that, as most of the SWS should have been accounted for by the 4.5h mark, adding sleep after it should allow more REM and light sleep to be gained, potentially easing the adaptation. However, during the adaptation, it may be somewhat difficult to wake up from a 5h core, before one gets used to the length.
