For almost 20 years now, I have written a lot about, and given numerous lectures on, IGDT. Yet, every time I do this, it is a new challenge, primarily because, unfortunately, I have to repeat myself, again, and again, and again. In this respect the current review is not different. I have done this before on many occasions.
Given the spirit and style of the book under review here (henceforth BOOK), I find it instructive, and necessary, to style my review as what I call “Reality-Check” (see the 2011 short post Info-gap decision theory: Reality Check).

And as usual, I try to make this review as self-contained as possible, and I do not assume that the reader is familiar with the core mathematical models of IGDT. The review often refers to the main three texts on IGDT, namely
