Time-averaged volume-weighted PDFs of log(ρ_d/ρ_g) for 3 μm (top) and 10 μm (bottom) dust grains in 256³ resolution where the one-fluid stopping time limiter has been adjusted to restrict St_num ≤ 0.5 (orange) and ≤2 (blue) at t/t_c = 5. A stricter limiter further enhances the coupling of dust to gas, restricting the range of dust-to-gas ratios, while relaxing the limiter correspondingly broadens the distribution.
