The tail of this vehicle is not the same as the base pressure recovery "box/cavity" referred to in the linked PDF.

For that particular mod to work, the "box/cavity" needs to be inset from the trailing edges of the vehicle, and extend out far enough to promote flow re-attachment, I believe, with entrained vortices in the "steps" between the sets of edges.
