According to Ray and Jan the cluster development in a spin glass can be described by calculating spin flip probabilities and by association of rarely flipping spins. We show that for the pure ferromagnetic Ising model the predicted Ray-Jan percolation transition temperature does not agree with the phase transition of the Ising system. Both diluted and undiluted Ising model show critical percolation spin flipping rates bigger that the Ray-Jan values.
