(Hopefully) My Final Word on the matter.

Got it.

The "Ultra Sayajin" was the one that got translated as "Assending Sayan" over here I personally never liked the name, I think the translaors took it litterally as "the next level" and never corrected it (since they never really use it again once they discover it's weakness)

Maybe SS4 was never given a name because it was made by the GT script which is slightly non-canon because it was made by a different person?

Anyway - Sorry for going off topic.
