To pursue more precise values for the scaling and northing errors of the Phillips 66, we can substitute for our previous method—one which used a minim…
But are you, though? I’m asking, because the location you have marked looks awfully close to what you would get if you used a modern accurate mappin…
Actually, I was using an old somewhat rough and ready map overlay. Constructing the same much more precisely, I do find that your candidate just creep…
Yes, it is easy to fall into misunderstandings over this, @Northkey. However, thankfully on this occasion my reading is intended to be precisely the s…
Hi Northkey. Welcome. Can you post an image showing where you understand your proposed solution to point to. Certainly, in taking the Phillips 66 to…
As a final analytic exercise, we ask ChatGPT to shift away from basic significance testing into the specifics of model comparison, forming a series of…
But, hold on. Have we not just taken our control analysis too far in the reverse direction? Is it really as damning to our original control analysis a…

Returning, then, to the original research question, which we posed as: Does the final line of the Z408 exhibit a degree of vertical copying from p…
Monte Carlo result retained The Monte Carlo test … asks how often a shuffled Z408-like grid gives the terminal 18 position a pull-down score at l…
Requesting ChatGPT to reconstruct and run the line comparison test, having dropped the constraint of only testing against lines above the line in ques…
But there are problems with this analysis, as proposed and run by ChatGPT. Most notably, it does not appear that we should be wholly satisfied with th…
Having been presented with the question as to what the analysis thus far helps us to conclude about the likelihood, or otherwise, of the final 18 ciph…
Conclusion Under this model, the Z408 final row appears to be a genuine statistical outlier. A fair summary would be: The final symbols of Z408 con…
