No issues with other metrics? To me all those metrics look like they are targeting work where every problem is well understood and people are just implementing primitive solutions and fix bugs. Or maybe just maintenance work. But not work where something new is created, actual problems solved or even just some amount of creativity involved, because then all the metrics will look abnormal and unpredictable.

Hi mrits! thanks your for your reply :)

That's true. The point w/ Code Churn is to have an approximation to know when there has been more flow of changes in a specific repository.
