I once was asked to count loc using a tool another team developed, to measure code produced in the last 3 months.

They had imported about a year's worth of crap from a previous repository 2.5 months ago.

I noticed that the loc counter included all commented loc, so I made a legit file of several tens of thousands "loc", checked it in, ran the counter, made the report, was recognized for productivity, and thn reverted the comments.

Productivity, largely, is reducing loc while improving other quality attributes and features...
