Just wanted to give an update that we have made good progress since this post was drafted to incorporate all of your feedback:

- all of the small fixes have been completed
- there have been a number of improvements to the trusted user model.

Bonus: If you want to see how the metrics are derived, we recently created [a lineage graph](https://models.opensource.observer/#!/model/model.opensource_observer.rf4_impact_metrics_by_project?g_v=1&g_i=%2Brf4_impact_metrics_by_project%2B). You can also view the logic and metadata about each model from [here](https://models.opensource.observer/#!/model/model.opensource_observer.rf4_impact_metrics_by_project#description).

Finally, let me just say that we feel immense pressure to do our part in making this experiment a success. All the feedback we’ve gotten on metrics has been so valuable – and your continued engagement is essential.

Thank you!
