Since the stars are near 1 solar mass and each has <10d orbital period, I think pairs should be nearer than Mercury to our sun which has 88d period.

Then the paper gives the separations of the systems as 18AU for the inner quadruple and 250AU for the whole system. That would put the inner system within the orbit of Uranus and the whole system larger than our solar system which has Kuiper belt at 50AU.
