I don't mean this critically but your product alarms me. I can imagine these reports being gamed and used to stack rank teams.
I am trying to be more open minded about your work but I can't understand how developer productivity could be measured with any of these metrics. I'm not aware of any prior work or research that shows that either. Writing software is a complex task and quantising it in this way seems reductive and problematic.
I would welcome being wrong about this. What am I missing?
