The manuscript is a resubmission of a previously evaluated and then released study. I evaluated the revised work of sufficient quality to be admitted to the discussion and review phase. All three Reviewers who accepted to serve on the work found severe drawbacks even with the current version of the manuscript. These range from (a) need to restructure the manuscript; to (b) some deficiencies in the proper justification of approaches. I have also assessed the responses of the Authors to the criticisms raised. While the totality of the Reviewers’ comments is pointing towards a direction which might lie beyond the concept of major revisions, I do think the Authors can be given a very last opportunity to revise their work. It has to be clear that in case the Reviewers will not be entirely satisfied by the Authors' revisions, the manuscript will then be unambiguously released.

I see no particular reason to delay acceptance of the study.
