Not fully, but I kinda get it.

I'm not fully sure I can reach NDAN limit, but I know I've passed the limit of PDAN and SDAN, and probably DAN as well. With the addition of multiple /'s, I may well have gone higher than NDAN but I need to plan out, I've only formally defined this so far up to zeta_0. But even if it only goes as far as DAN, it's still a pretty powerful function.
