Agree fully. Yours isn't the case I'm talking about. I'm talking about the people that aren't hunting big bugs, aren't serving as advisors or architects, aren't deleting unused code, and aren't implementing a significant volume of features or functionality, but who instead trickle out a small amount of simple code month after month. I claim that when inspecting commit histories, a very low LOC or very low commit-frequency is something a manager should look into.
