If this study is measuring that way, it is completely ridiculous. To
test if something is a bug, you have to compare behaviour to specification.
But if a specification is not there, then you cannot compare in such a way
at all. Apart from the fact, that such bug per loc nonsense is ridiculous
anyways.
