When you start with silly metrics to arrive at faulty conclusions.
Yes - number of commit is inversely relational to stability and reliability. Code-churning is a great big honking red flag. Commits should be only very well-considered
Consider that this metric included all (as many as they could find) open-source projects directly/primarily related to a BCH. Not just protocol / node implementation development.
