Yes, she says so. She also says he's faster than her. Two separate things. And there is NOTHING to suggest that her not being able to read his movements somehow shatters her confidence to the point that she can't tell if someone is faster than her or not.
@cochise: Its questionable. She can't beat Slade in a fight because she can't read him, that's why she THINKS he's faster.
@cable_extreme: What Jashro said. She relies on her body reading in fights, without it, she loses confidence. Slade negates that ability, she loses confidence when fighting Slade. I'm not taking away anything from her speed, she's still the fastest cat here.
There's literally no reason to think this is the case.
@cable_extreme: What makes me think what? The fact that Cassie THINKS Slade is faster? I've already tried to explain my reasoning. Its because she can't read Slade. Slade's fast, but Cassie (by feats) is faster.
Why would Batgirl be wrong about her estimation of Slade's speed? She's not a moron. She explicitly says that he's faster than her, IN ADDITION to saying she can't read him.
Wolverine also has enhanced resistance to nerve strikes, as conclusively demonstrated in Frank Miller's mini, where he endured numerous nerve strikes that would kill a normal human, and which only caused him pain.
