In the grand scheme of thing it is a very minor thing for a guy to be bumping his thread when he believes (with evidence) that he has cracked the Mount Diablo code, and is trying to inform the public.
This should be expected from someone that has solved this cipher.
I have reviewed other proposed Z32 solutions almost all of them are bad except for Olivs.

And that is why I will always mention Oliv92 positively in their work on the Mount Diablo code. They earn the honorable mention due to their good modeling. They may have picked the wrong candidate, but their approach was logical.

I feel that Oliv92 was one expert comment away from cracking the Mount Diablo code. Cannot say with certainty however. But yes more should have been talking with them.

While I don’t love the forum environments, my work has educational value and historical significance. Depending on what may be buried there, I have made the greatest contribution to the Zodiac case that has ever occurred.
I don’t know if that is true, I am still sitting around.
But let’s remember this in case it turns out to be correct. My work was censored and not engaged with in a meaningful way, but rather treated as insignificant. That is fine, I am just waiting for the scan.

The most important thing, beyond even the plaintext, is my discovery of the triangle landmark by LHR. It’s relationship to my solution is epic, but the landmark transcends the cipher.

@shaqmeister can object until the cows come home, I am the finder of the triangle. I already checked after finding it, if anyone else had discussed this landmark by LHR. I could find no evidence of it ever being discussed. I did find the plaintext of course, with half baked methodologies that incorporated subjective beliefs, and no triangle landmark identified.

He can say the correct Z32 solution lands at Twin Peaks, that is nice. I found the triangle by LHR.

To the best of my knowledge, I am the first person on the internet to ever identify this landmark. If someone did ever discuss it, please find that link for me. If they did, they did not solve Z32 as well. I would have found that already after the fact.

People can debate the validity of my solution. That is nice/cute. I found the landmark. Facts.

For the sake of transparency Obama did not endorse my solution (yet).
I didn’t bother to inform him of my accomplishment as I know he is busy.
