I wouldn't be so sure, if she sneaked up on Heizenberg she'd probably knock him out with one punch. Straight up fight he'd try not to let her get close which is relatively easy for him (still she might hurl a few cars) but her "strength" in melee combat is a threat to him, its where he's a bit weaker and if she sneaks up she'd take him down with one hit, a bit of experience and she sounds like she could be scary, especially if she starts using her powers without the restrictions of her perceptions.
