If all you can get is problematic data, then remove the metric. It doesn’t make any sense to compare “core repos” because different teams may have different development patterns, where one team may have a more monolithic approach and the other would have a more modularized approach. If you’re thinking, why on earth would you want to go with a huge, monolithic repo, then you’re hitting on the core of the issue here.\

Remove the metric. It is an inaccurate distraction.
