The first glyph of every line – a hint at a cipher?

[JoJo_Jost]

This is speculative. If we had a solid rule (supported by strong evidence) that the way a section/page/paragraph/line starts (first character or gallows or sequence of gallows or whatever) has some consistent, measurable effect on some statistic over the rest of the section/page/paragraph/line, it would rule out the notion that it is random and hint at some kind of key or change of process. But we don't. So it could be... So far we have only the Vertical Impact Effect™ proving that the sequence of first characters of lines is not random.

I'm not quite sure I understand you correctly. Are you saying there's no statistical evidence to show that the text in the individual sections (Herbal, Astro, Recipes, etc.) behaves differently than in other sections? I actually thought that was common knowledge? There are a lot of interesting differences, although of course the label-heavy sections differ significantly, which is naturally difficult to evaluate... But even the text-heavy parts have distinct differences among themselves that are limited to the sections. 

I’m asking because if I post these statistics here, I’d have to have them all checked, which is a lot of work...
