Ok, starting from the top with the power grid:
Intelligence: 4 Gifted It's quite clear from her description she's intelligent but with no super gadgets I'd suspect she's just shy of genius level.
Strength: 3 Athletic she doesn't look super ripped and there was no mention of super abilities so from that picture I'd just go with her being able to lift twice her body weight.
Speed: 2 Normal no flight or superspeed abilities mentioned
Durability: 2 Normal she heals like anybody else
Energy Projection: 1 None, as far as I know she has no energy powers
Fighting Ability: 4 Experience Fighter I don't think she'd be a hero if she didn't think she could handle herself, but I don't know if she's Mastered a Single Martial art (That takes a lot of time and she seems pretty young.)
This is my judgement, feel free to discuss and maybe we can find just the right levels for her.
