From Frieza, Cell, and Buu (none of whom she faced solo) all the way to the likes of Beerus (a test where he clearly held back) and Demigra (won, but needed the ki of her mentors to finally overpower him), I'd say she needed Super Saiyan transformations to stand a chance, or to at the very least make things easier.

As for what that means for her base form power level-wise, I can't say for sure, though I'd imagine it probably improved steadily so as to help her transformations grow as well. I'm open to whatever interpretation of her power level you have.
