No, it's just that Tad is trying to sell flawed logic as being a matter of fact. Let me explain what he isn't telling you but what he certainly knows if he has any true understanding of the process he has employed.
There are 936 letters on his spread sheet, only 26 letters in the alphabet, so the entire alphabet can be placed in this space a total of 36 times. Concerning the alphabet, there are rules that govern its use, this being a factor that will dictate a large portion of the letter arrangements on the spread sheet, especially when and where curious arrangements might seem to appear, those arrangements often not as curious as it may otherwise seem.
Note that in the example he has offered there exist “many” such curious arrangements that are not being detailed, the question is why? The answer is simple, those other curious arrangements don't fit into the premeditated scheme of things. In his spreadsheet only those curious arrangements that do fit into the premeditated scheme of things are being highlighted and detailed. Up, down, left, right, catty-corner, every other space, and so on and so on, seemingly curious arrangements can be found all over the spreadsheet. Why then are these other curious arrangements of less value to the creator of this particular spreadsheet? Why do only the ones he has highlighted bear any value? Again, the answer is very-very simple, because those he has highlighted do fit into his premeditated scheme of things and the others don't. It's pretty straight forward basic 101 stuff.
Per example, Longfellow, Cooper, and even James Patterson, the same type of case could be built against anyone of them from the same exact spread sheet if someone chose to spend enough time manufacturing similar fictional evidences against them. It's not what you're being shown that's important, it's what you're not being shown that's important.
