For fixed radiative efficiency $\eta$, Eddington-limited <accretion> without mergers gives $M(t)=M_0e^{t/t_{\rm Sal}}$ with $t_{\rm Sal}=\eta\sigma_Tc/[(1-\eta)4\pi Gm_p]$. A specified final mass and growth interval therefore require $M_0\geq M_fe^{-\Delta t/t_{\rm Sal}}$. The retained factor $1-\eta$ distinguishes actual hole growth from rest-mass supply.
