LOL No kidding! Im still wading through the reference papers and the original paper, but one thing is clear to me.
Assuming those folks all actually know something about hydroponics, and growing in general, and that they are at least somewhat educated in those fields - in other words, that they are really experts, then its clear that we as pot growers are way out in left field! 
Like you said, the terminology they use and quite a few of the techniques they describe, are very different from what we generally do. Some of it is difficult to figure out, partly for that reason, plus the terminology seems to be different in many cases.
Its still very interesting reading. Some things are not what I expected and there seems to be some conflicting conclusions, but that may be just me misunderstanding parts of the papers.
Im going to keep wading…
Thats one of the problems Im having as well. So far I dont get where their reasoning comes from or is going with that. I have not had time to look into it at all though. They seem to assume everyone knows all about it already
