Most flying wings have surface area that does not provide lift.
In fact  some part of the rear part of the wing must provide down force
since the CG remains ahead of the center of lift.

Sounds just as efficient as the horizontal stabilizer to me!

It is the part between the front of the flying wing and the back of
the flying wing that is going along for the free ride.
