Changesets vs Revisions in Crucible's Review Coverage Overview

Question

With the Crucible's Review Coverage Overview, what is the difference between what is being measured on the Changesets tab and the Revisions tab? I've looked around and found conflicting statements on the difference.

Our setup is tired into Mercurial, if that is important.

Also: what is meant by, "A changeset is only considered reviewed if all revisions are in review"?

A changeset can include changes to multiple files, and Crucible permits you to remove specific file changes from the review after adding the changeset. I would guess that quote means that if you remove changes to any of the files, the entire changeset is no longer reviewed.

I found the standard coverage reports lacking, so developed a branch-based report, Flyover, which is on the Marketplace if you are interested.
