Following the training, I think it would be valuable to have an example exercise where someone can take a letter excerpt that have specific issues and apply the review process to it. Following that, they can compare it to a "exemplary result" and see where and how they differ. There could also be exemplary steps along the way - gender bias editor, highlighting, fixing grammatical and formatting errors, and including comments - so that perspective reviewers can check their work. This would be valuable for workshops as well.
