Chunin are not ridiculously skilled. They are essentially an average reliable ninja.

You can expect a Chunin to know how to act in the field, and you can expect a Chunin to step up when necessary. They won't be the strongest on the battlefield, but they're consistent and reliable.

Unlike Genin, who generally aren't as logical and don't make the most rational decisions in the field usually. Genin may have the power or combat ability of a Chunin, but what separates them is their experience and the ability to properly react to unique situations in a consistently logical manner.
