A disquieting thought

[obelus]

Another example of single-scribe variation is the prominent excess (new to me) of EVA:al in f58, which is not observed in q20 (Starred), although both are attributed by LFG to Scribe 3.  On the left is a density map of EVA:al in paragraph-style text over the entire ms, with rows indexed by line number and columns indexed by first-character position in the line:

   

The stripe of high density at lines ~1400-1500 is f58, while q20 spans lines ~3200-4200.

MarcoP's example of EVA:eol is mapped on the right.  Big Pharma covers lines ~2900-3000, while the entire Herbal section spans lines ~0-1600.

The resolution is 50 lines x 2 characters, or 100 EVA characters/bin.
