Current state: https://mui-dashboard.netlify.app/test-profile/199723

These are not ordered by their implementation timeline but as a convenience for referencing individual work-items.

1. MVP (https://github.com/eps1lon/mui-contributor-dashboard/pull/21)
2. link to CircleCI run With https://github.com/eps1lon/mui-contributor-dashboard/issues/28 we link to the GH PR from which the job is available. Might be sufficient. But https://github.com/eps1lon/mui-contributor-dashboard/pull/28 already provided the data so that part is at least done.
3. link to test (https://github.com/eps1lon/mui-contributor-dashboard/pull/25) Implemented by tracing.
4. deduplicate phase
5. more analysis (e.g. percentiles)
