  We numerically calculate the exponent for the disorder averaged and
fixed-sample decay of the energy-energy correlator in the q-state random-bond
Potts model. Our results are in good agreement with a two-loop expansion
(cond-mat/9910181) around q=2 recently found from perturbative renormalisation
group techniques, fulfill the correlation length bound \nu >= 2/d, and give
further evidence against replica symmetry breaking in this class of models.
