Dumb study, IMO. Often the value of refactoring is to promote re-use of the code (generally by adding flexibility), but that comes at the cost of some additional complexity. I don't see that any of their metrics measure that. But I guess the lesson of the paper is, don't refactor for the sake of refactoring, which should be obvious.
