Currier A/B split is not what we thought it was!

To me, the most intriguing finding is that these two signals are completely orthogonal. Within the Herbal section, the correlation between the cho/che ratio and the d/l ratio is essentially zero. Knowing the switch state of a folio tells you nothing about its d/l ratio, and vice versa. They are independent dimensions of the manuscript's structure, driven by separate mechanisms that happen to partially align in Currier's coarse classification.

I don't think I understand most of this, could you maybe explain the implications a bit more? If the "signals" do not map to A/B then are we just talking about some arbitrary split of folios into groups and then identifying some metric orthogonal to this division? What's the use of this? I think you mentioned some "structure" that this approach unveils, what is this structure?
