I would like to point out or add to your comment in your article which maybe be something to ponder on.
"I personally not only find it interesting, but significant to note that despite no fixed theory, no Muslim(s) has ever tampered with the letters, edited it or removed it from the scripture. "
It could also mean that it shows that even every single letter is protected and guarded by GOD. And that no one has the authority to change even a single letter.
Yusuf Ali
We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption).
