Editors, how many do you use for each project

[Seamus]

Just curious how many editors others normally hire for their projects. Is it okay to have a single editor take care of big edits and the copy edits?

In most of the projects to which I have contributed, one editor has been sufficient. For the Dresden Files RPG, however, Evil Hat is using two or three editors. It's a big project.
