Pull Request Usage
The percentage of active repositories located in organizations, having more than one contributor, and using pull requests for contributions.
In this context, active designates repositories with at least two users that have pushed commits in the last four weeks. The rationale behind this is that pull request usage is most important in a collaborative environment.
High pull request usage might indicate a high number of code reviews.
For reference, the percentage of status usage in these pull requests is visualized.
High status usage might indicate high CI usage.
Repositories in personal accounts and repositories with a single contributor are ignored, as they are less likely to use pull requests.
