For the critical focusing wave equation□ u= u 5 on R 3+ 1 in the radial case, we prove the existence of type II blow up solutions with scaling parameter λ (t)= t− 1− ν for all ν> 0. This extends the previous work by the authors and Tataru where the condition ν> 1 2 had been imposed, and gives the optimal range of polynomial blow up rates in light of recent work by Duyckaerts, Kenig and Merle.
