I didn’t explain it because I didn’t write it. Why don’t you ask the guy who did?
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.
