It seems to me that while any one of those metrics isn’t particularly useful in isolation, if the same person is consistently at the top of all of them, that’s telling you something.
Maybe. but what if their peer has far fewer commits to their name, far fewer written unit tests attributable to them, because they spend most of their time using their indepth domain knowledge to assist other developers, who then make commits based on that contribution?
Do they have to sit around and ensure that their coworker includes a "Co-Authored-By" in the commit message? One commit message? All commit messsages? etc. etc.
This guy was also top in terms of the number of FAQ entries written to help people. In fact he wrote the FAQ system itself and also wrote a right-click plugin so if you rightclicked on a question in chat it would auto-search the FAQ.
_What_ it tells you, however, depends on whether or not the combined metrics are used to evaluate people (or more accurately, whether people _think_ they're being evaluated by those metrics). Goodhart's Law[1], ruining everything since 1975.
