Dynamical separation distributions for the three combinations of interacting planets. We observe that all three combinations have Δ > 12 by a relatively wide margin. A priori, interactions between HD 190360 c and HD 190360 d would be expected to be the largest, and so their Δ distribution being the highest is a promising indicator that this configuration of planets would have been long-term stable.
