I'd hardly call this a "mid diff", Zoro is going beyond his limits to push out CoC at the risk of his life.
Pre FS WCI Luffy landing a few King Kong Guns on King would take him down very quickly too, wouldn't call that mid diff.

Zoro would have defeated him even without CoC coating attacks if he had figured out about Kings powers but he would have needed an extreme diff fight
