3dttest++ -Clustsim P-value question

I am hoping that someone can clarify whether I need to use a p-value of 0.01 when using the new ‘3dttest++ -Clustsim’ option, or whether I can use p=0.05. Based on the recent article in Brain Connectivity called: FMRI Clustering in AFNI: False Positive Rates Redux, the data appears to show that the FPR does not exceed 5% for p-values of .01 through .001, but there is no data presented for a p-value of 0.05. Can I assume the same FDR holds? Please advise. Thanks so much!
