Cool - thanks! While the measures a simple in theory, there are some practical challenges; git repositories tend to be messy. So part of the practical challenge is to clean the input data (e.g. filter out auto-generated content, checked in third party libraries).

Another challenge is that version-control data is quite file centric, while many actionable insights are on a higher architectural level. In CodeScene we solve this by aggregating files into logical components that can then be presented and scored.
