Actually, I find LoC estimates can be quite good at determining the
number of person-hours required. I first learned how to estimate them
when working for IBM, and have used them successfully as a consultant
for a number of years.
The secret, however, is to get an accurate estimate. It's not easy and
takes a lot of experience (as well as a good set of requirements).
