In some cases, it can take long for a bulk review package to be completed, and the author might get impatient and unhappy. For these special situations, we could have a small group of trusted reviewers who read the book and deliver the review relatively fast. To address a review assignment to the members of this group, the average turnaround times would have to be already exceeded. To become a member of this reviewer group, the reviewers should be level 5 or 6 and commit to completing these special review assignments within 2 weeks' time.
