We investigate the convergence rates of numerical schemes for degenerate convection diffusion equations. Recent results bound these rates as 1/3 in one space dimension and 2/(19 + d) in several space dimension. In our numerical experiments, we obtain much better rates, indicating that the theoretical bounds are not optimal.
