Signatures of the cluster spin glass have been found in a variety of experiments, with an effective onset temperature Ton that is frequency dependent. We reanalyze the experimental results and find that they are characterized by a distribution of activation energies, with a nonzero glass transition temperature Tg(x)<Ton. While the distribution of activation energies is the same, the distribution of weights depends on the process. Remarkably, the weights are essentially doping independent.
