That's pretty much what I told the PM in my example. Several times
over. I told him I judge progress on the number of
features/requirements which have been completed successfully, not how
many times I hit the Enter key. Even explained that sometimes I'll
remove lines along the way because I found ways to re-use stuff I'd
written before. Didn't matter. He liked raw LOC numbers. My guess is
he was comparing notes with some of his friends about their
programmers.
