Sorry, I thought you were defending the author’s method. My point is that there have been several, very unscientific, “analyses” of the various COLB images. You can’t do much with a compressed source image. It would be better, IMHO, to concentrate efforts on securing peripheral documentation (school records, etc.) which may yield new information about Dear Leader.
If you decide to look at what he did and offer an informed analysis of it please ping me to it. I don’t have the technical knowledge to do that but I can follow a well written explanation and discern its credibility.
