There is basically an infinite number of patterns which a person with religious or other motivation could read significance into. The number of possible 'hits' for some pattern or other is huge for a book of 80,000 words, and especially so for one so repetitive. It's not as if the miracle seekers decided beforehand that this type of pattern was particularly significant. They found the pattern. Any pattern would do, and then read significance into it. It would be more surprising if such patterns could not be found.
Of course, when the word 'middle' is not in the middle of the chapter for example, they just literally ignore that, so there is no such thing as a miss. It's the same basic strategy as the bible code, and even the Moby Dick code. http://users.cecs.anu.edu.au/~bdm/codes/moby.html
If for some reason people thought you were a prophet, and for hundreds of years people have been spending every waking hour analysing every letter and dot of your comments, all sorts of interesting patterns would be found. Interesting that is, to your followers. Totally mundane to everyone else.
