Thanks for the great effort you put in that. Point is well made, and I'm allowing for certain margins of error. I do think the wnd letter differences are more pronounced, but there may have been more scanning iterations, and I can't look behind the curtain and see the exact processes used and am further hampered by the fact that I don't have any grasp of Illustrator or how .pdf documents are prepared for the web. If I had to put one together, I'd figure out how on the fly like I do most everything else because you can get lost in the details and minutiae and not get what you want done.
All my software apps I learned like that, just decided to do it and did it. Adobe products like Photoshop are not intuitive, and it was tutorials that got me started, help on the web and just playing with the various features. I finally took a course in CS2 but have forgotten features I don't use regularly.
I believe that the further analysis helps to reinforce the exposure of the fraud, since it does not show any variance in fonts. You will find the same evidence in the Nordyke certificates which would have been processed at the same time, yet are inconsistent with the 0bama BC.
