Why would it still be a "currently running project"?

As I understand it, each WU is only a small piece of the entire project. I have two CPUs working on 1809 (again) right now.

That's right. When one finishes a work unit you have not figured out every possible combination of folds for a protein, but only a very specific subset of folds for a molecule that makes up the protein.

Also, I understand that several folders will work on the same work unit for an integrity check. Sometimes the folding answers are physically impossible, sometimes the answers have small errors that creep in.
