I completely agree that the documents are frauds. I think the issue is that the documents were typed with the default Word margins. Just tried it myself, and at 1.25 left and right, using Times New Roman, the document formats exactly as the forged memos.
In sum, the cleanest, clearest, and most elegant explanation--the only explanation that fits all the evidence without being forced unnaturally--is that the document(s) were prepared with Microsoft Word at either its default 1.25" margin setting on 8.5 x 11 paper or one-inch margin setting on 8 x 10.5 paper.
Admin moderator, you might want to pull this until I can rewrite it to bring its accuracy up to speed.
