Our study is conducted for $N_f = 2+1+1$ QCD with physical quark masses, discretized via stout improved staggered fermions and considering mostly two different values of the compactifed dimension, $N_t = 8$ and $N_t = 10$. Results for $T_{RW}$ and for the associated universality class are consistent with those found in the $N_f = 2 + 1$ case with a slightly different discretization.
