Predicted local rate of GW190814-like mergers, R_GW190814 = f_m R_LGRB (Equation (A1) with ϵ_fragϵ_LGRB = 1), for f_m  =  0.01, 0.05, and 0.10 (top three rows), compared with the measured LVK rate for GW190814 (bottom). The shaded band marks the measured 90% interval (1–23 Gpc⁻³ yr⁻¹) and the dashed line its median (7 Gpc⁻³ yr⁻¹; R. Abbott et al. 2020); predicted rates use ﹩{R}_{{\rm{LGRB}}}=7{9}_{-33}^{+57}\,{{\rm{Gpc}}}^{-3}\,{{\rm{yr}}}^{-1}﹩ (G. Ghirlanda & R. Salvaterra 2022). The f_m  =  0.05 and f_m  =  0.10 cases overlap the measured posterior, while f_m  =  0.01 lies at the low-rate edge.
