The dynamic structure factors S(q, ω) of an ideal percolating network, the three-dimensional (3d) dilute Heisenberg antiferromagnet RbMn_<0.4>Mg_<0.6>F_3, obtained from high resoluton (ΔE=17.5μeV) inelastic neutron scattering (INS) experiments are analyzed for the first time within the framework of the single-length-scaling postulate (SLSP). The analysis confirms the validity of the SLSP and is also used to extract the values of the key exponents governing the spin dynamics, the dynamic exponent (Z_<AF>=D_f/d_<AF>) being 2.5±0.1 and the spectral dimension d_<AF> for antiferromagnetic (AFM) fractons taking a value of unity.
