Left panel: cumulative distributions of Symphony subhalos’ z = 0 virial mass, M _sub, divided by the largest virial mass achieved along each subhalo’s main branch, M _peak,sub, stacked over all subhalos from each suite with M _sub/M _host > 2.7 × 10⁻⁴. Right panel: same as the left panel, for the ratio of z = 0 maximum circular velocity, ﹩{V}_{\max ,\mathrm{sub}}﹩, to the largest ﹩{V}_{\max ,\mathrm{sub}}﹩ achieved along each subhalo’s main branch, V _peak,sub.
