I agree that LOC isn't an ideal metric. But there isn't really an ideal simplistic metric. Out of curiosity, I thought I'd look at a recent productive day. In actual numbers, my 42 check-ins totaled 409 new lines of code compared with 213 lines deleted, so close to 50% (not counting check-ins with simple line changes). At the end I had several new features implemented and a lot of code refactored to be cleaner.
