I agree that we were given a map, and that working with that map is the obvious starting point.But I think you are overlooking how much of the Phillip…
There is nothing inherently wrong with your three-step interpretation. It is a perfectly reasonable approach. But I don’t see why it should…
As you yourself pointed out on page 1, the Phillips 66 map has both a north-alignment error of approximately 5° and an actual scale of approximately 7…
But couldn’t the same question be asked of the cipher itself? Why didn’t Zodiac simply provide the entire instruction in plaintext?  …
I think your broader point about putting ourselves back into a 1970 mindset is a good one, and I agree that we should not expect modern GPS-level prec…
I’ll try to address both of your posts together here. In 1970, the natural reaction to receiving a paper map and a result expressed in inch…
Thanks. I think there are three separate issues here. Firstly, I agree that it has more recently been shown that the Phillips 66 map’s actual ge…
Why must the Phillips 66 map be the final plotting surface? My interpretation does not use it that way. The map supplies the orientation and scale r…
Thank you, @shaqmeister. I agree that this needs to be defined more precisely. The statistic I have used is not the set of all pairwise distances be…
Clarification: P66 may be the key, not the plotting surface When I first posted my Z32 candidate, I assumed that SIX INCHES had to be measured physic…
I think I can now clear up the point we were discussing about Neary and the Phillips 66 map, and there is also a new development in the cipher hypothe…
The part I am still trying to understand is the discrepancy between your direct Phillips-map plot and the independent geographical check. Geographic…
Thanks. The point I’m proposing is approximately the Neary/Sondgrath quarry area in Los Altos Hills, which I’ve marked on the Phillips 66 map. I thi…
