What data is included in Time to first comment?

A pull request is counted toward Time to first comment as long as it is merged and has a comment before it’s merged. It does not matter whether it’s merged from one feature branch to another or is merged into the main branch. Only pull requests with non-zero values for Time to first comment are included in the calculation.

Pull requests are not counted toward Time to first comment if:

  • they are created by a user who is excluded from reports

  • they are created by a hidden user

  • they are an excluded pull request

  • they are from a deleted repository

Comments on pull requests won’t be counted toward Time to first comment if:

  • The comment is excluded

  • The user making the comment is excluded from reports

  • The user making the comment is a hidden user

Note: User view rights and permissions also impact how specific users will see Time to first comment.
