P.S. The V(a) formula I was talking about can be found here (NNTDM, 27(4), pp. 43-61): The congruence speed formula.
For every radix \(r\geq 2\), the congruence speed of tetration stabilizes at a positive constant for all bases \(a>1\) with \(\mathrm{rad}(r )\nmid a\) if and only if \(r\) is squarefree. (NNTDM 32(3), Appendix B)
