What is this metric?

The average code changes (in Lines of Code) of PRs in the selected time range.

Why is it important?

Small PRs can reduce risks of introducing new bugs and increase code review quality, as problems may often be hidden in big chuncks of code and difficult to identify.

Which dashboard(s) does it exist in?
