Q: The status “evaluating reviews” goes beyond 20 days. What does it mean?
The status "evaluating review" means that the editor/editorial board has received the review reports/peer reviewer comments on your manuscript and is now examining them to decide on the next steps. If the editorial board is satisfied with the reviews, it may take a decision. If it feels that one or more of the reviews are weak or if the peer reviewers have conflicting opinions, the board may send the manuscript for an additional review. The next status update should give you a better idea of manuscript status.
