Pareidolia can be automated too...  Like the sorting of books by height...

I see a ton of plots in that linked post but don't understand where I should look for the overlap values etc.  Still trying.  Meanwhile, have you noticed these two points?

But I did notice an interesting correlation. On the pages where the second parag is split by a narrow plant stem, the left text rail seems to be strictly parallel to that stem.  See f8r, f49v, and others.

Wow look ... at these sequences here. The section on the left splits and gradually separates before snapping back.

But you observed yourself that the text is split only when and where there is enough room to the right of the plant. And that obviously depends on the plant more than anything else.  Even because the plant is often pushed to the right in order to leave space for the text.  And when there is no split, the right edge of the text is determined by the plant's profile

All the best, --stolfi
