It is a task that gets little time and investment, as development goals are not report oriented, they are product delivery oriented. I’ve attempted to capture some of the more mundane details, and set aside future report details that require a larger effort. I’ll be describing what I’ve done to create the reports, but not really discuss about why or how to interpret the data. A discussion of some other data and what you can do with it can also be found here.

One thing I've found with data like your churn information is that it is not just a candidate for reviews, but a strong indicator that to much functionality is found in a single file, especially if the changes are distributed across multiple developers. Some factors I've found are: Methods are overly inclusive, used for lots of tasks. This (for me) is a strong indicator that they are prone to more subtle bugs, and besides reviews require stronger testing methods and are likely to cause regression errors. Great candidates for refactoring. Methods aren't being distributed in the object model. Subclassing, creating more task oriented classes can make the code more usable both when adding more functionality and reviewing during development.
