  In previous work, arXiv:1905.01909, we have calculated the $m_\varrho /
f_\pi$ ratio in the chiral and continuum limit for $SU(3)$ gauge theory coupled
to $N_f = 2,3,4,5,6$ fermions in the fundamental representation. The main
result was that this ratio displays no statistically significant
$N_f$-dependence. In the present work we continue the study of the
$N_f$-dependence by extending the simulations to $N_f = 7, 8, 9, 10$. Along the
way we also study in detail the $N_f$-dependence of finite volume effects on
low energy observables and a particular translational symmetry breaking
unphysical, lattice artefact phase specific to staggered fermions.
