Eh, I hoped we have, once for all, concluded that within standard rules for fundamental sequences catch-up point is psi(W_w).

I think fundamental sequences go like this (I can be wrong): theta(w+1) -> theta(w,theta(w,...theta(w,0)...)) (with n theta's) -> theta(w,theta(w,...theta(n,0)...)) -> (something bigger than theta(n+1))
