As a team we have been trying to use Code Cycle Time metric to measure how long it takes for PRs to close; however, we find that these metrics vary from sprint to sprint quite heavily due to the fact that some PRs are open on Fridays and don't receive feedback until Monday for example. Also if a PR is opened in the morning vs near the end of the work day that also makes a difference. Is there any way that Plandek could account for Weekends and working hours?
