My general conclusion is that this paper should be published in its present form with only one correction to the references (see below). In general author has done an excellent job of responding to reviewers including my own previous comments. This is a very strong paper which is sure to make an important and lasting contribution to the literature. The author is to be commended for his diligence. His competence and deep grasp of the material finally I believe shines in this re-write. I would further like to explicitly support his response to the other reviewers as well both in places where he has made requisite changes and other places where he has held his ground with the necessary argument and illustration. In all of this he has done an impressive job. Not just the author, but the Editor as well as the other reviewers all deserve credit for their perseverance. The result I believe has been worth it. Reference correction: In my first review of author's paper I noted that where he cites Swenson's "problem of the population of one", an important idea for his paper, he cited a paper that did not have that in it. In his subsequent revision he cited a paper for this point but which my experience suggests is not widely accessible. In my re-review I said as much and suggested several very accessible papers of Swenson's that make this point. In this re-write author is now citing a paper which does not contain this idea, although it is a paper I recommended be included as the minimal paper that should be cited for Swenson's more general points and his 'law of maximum entropy production' as correctly discussed by the author. So here again below are the notes on citations that were included with my last review. Author should pick one (but not the first) from the first list for the "problem of the population of one" point he makes (on page 2) and then use the Swenson (2000) paper for the law of maximum entropy production and other general points he cites. He should also use Swenson's 1989 paper as he uses it for the first time as he does when he mentions any of the general points (along with the 2000 paper). Neither of these papers though mention the "problem of the population of one," It is important to use the 1989 paper since this was the first widely published article where the general ideas of Swenson's were published but it is important that the 2000 paper be cited as a general reference for these ideas since the 1989 paper does not express the main principle the way it came to be expressed in almost every subsequent paper afterwards (from 1990 on). In short, author needs to add an additional reference to Swenson that covers the "problem of the population of one". He needs the other two references (1989, and 2000) exactly as he uses them for Swenson's "principle" and the other general ideas of Swenson's he appropriately discusses and articulates.
