\caption{Extrapolated $1\sigma$ uncertainties on $H_0$ from GW memory, scaled to the expected number of detections via $\sigma(N)=\sigma(N_\mathrm{det})\sqrt{N_\mathrm{det}/N}$. Each cell shows the mean $\pm$ population scatter $\sigma_\mathrm{pop}$ (astrophysical variance across event realisations), with the error on the mean $\sigma_\mathrm{err}$ (Monte Carlo accuracy) in parentheses.}
