Keeping all systematic effects under full control we find no statistically significant $N_f$-dependence; $m_\\varrho / f_\\pi = 7.95(15)$. Assuming the KSRF-relations we conclude that 3 other low energy quantities related to the vector meson are also $N_f$-independent within errors including the $\\varrho\\pi\\pi$ coupling $g_{\\varrho\\pi\\pi}$.
