No, the codes were only tried on the version we have, but even if it were tried on a thousand and worked, we would (if the math is humanly impossible) say Hashem put it in all. Also, what you call “by accident”, I call by hashgachah pratis. I believe Hashem has the ability to orchestrate how our sefer Torah appears. Don’t you? It could even be that he arranged for the codes to b’davka be in the version we have at the time the codes would be discovered, as a kiruv tool. This is all conjecture to answer a kashya oif a maaseh.
The Christian coders might be quacks as well. I don’t know or care. I don’t believe the experts Aish quote are, though. Might they be wrong? For the sixth (?) time, I don’t know, and I do not wish to form an opinion about something which requires expertise but I’m not an expert at.
“If”. Please don’t misrepresent my clear statement and position.
