Based upon 26 years involved directly in pre-press operations both film based and electronic, I can attest with 100% certainly that the site you posted has it wrong and this document is a complete poorly done forgery.. A person with just one year of experience would be able to spot all the edits.
Even without everything they tried to disprove (which they did not) I based my assessment on edits completely different.
I downloaded the document right from the White House site and the very first thing after opening it in Adobe Illustrator was over 25 layers of edits. Now a few layers might be expected for re-sizing and maybe adjusting the brightness or contrast level. So maybe 2 or 3 layers would not be unusual.
Looking at items like the signature which when enlarged will show a dark center line and as you look to the edges of a REAL pen/pencil line you would expect to see pixels get progressively lighter.
This was NOT the case in this forgery. There were partial segments of the signature which looked normal but the majority of the signature was solid black which is an obvious manual edit by a very lazy person. They simply picked black as the color then tried to make the signature look like what they wanted. The line was solid black with no gradual graying of the pixels. Just in this case it is 100% fake.
If anyone doubts what I am saying just sign your name in pen/pencil on paper then look at the line under enlargement. You will easily see how the pen/pencil line is never fully solid from center to the edges.
There were also letters typed which suffered from a similar problem. A typed letter will have less of a soft transition from solid black to transparent but you can easily see some numbers/characters were just solid black which again is a manual edit by a very lazy and unprofessional operator. These edits, to an untrained eye simply look like they were typed on a different machine. They were manually edited 100% certainty.

This is important and significant evidence to tampering on a higher level. Again... the current report explains all of this.
