Maybe the scheme could get more elaborate yet to prove the

No need, even someone as stupid as you should be able to grasp
that the primary system will have the effect of spreading the effect
of the single ductless split system thruout the house if its put in the
main living area.

In effect the ductless split system is just like the strips except that its
much more efficient than the strips for when the primary system doesnt
have enough horsepower to come back off setback quickly enough.
