In Hamers & Samsing (2020; url), we study the gravitational effects of scattering of two binaries in the "weak" limit, i.e., in which the two binaries approach each other at a relatively large distance. We find that, to good approximation, one can use previous analytic results for binary-single scattering in the weak limit, and replace the mass of the single interloping body with the total mass of the interloping binary. In other words, the point mass approximation works well for weak binary-binary scattering.
