That would mean the within-scribe variation exceeds the between-scribe variation, which is hard to reconcile with a multiple-scribe model but follows naturally from a continuous evolutionary gradient.
I ran the comparison you suggested, and yes, your prediction is technically correct — but the separation is not large.
Using Zandbergen/Landini:
| comparison | Pearson | cosine |
|---|---|---|
| S2 Herbal B vs S2 Quire 13 | 0.918 | 0.928 |
| S2 Herbal B vs S3 Quire 20 | 0.942 | 0.949 |
| S2 Quire 13 vs S3 Quire 20 | 0.926 | 0.934 |
Using Takahashi, where my other computations are from:
| comparison | Pearson | cosine |
|---|---|---|
| S2 Herbal B vs S2 Quire 13 | 0.887 | 0.898 |
| S2 Herbal B vs S3 Quire 20 | 0.945 | 0.951 |
| S2 Quire 13 vs S3 Quire 20 | 0.925 | 0.931 |
So, yes: S2 Herbal B is closer to S3 Quire 20 than to S2 Quire 13 in both transcriptions.
But the size of the effect matters. In Zandbergen/Landini, the Pearson gap is only 0.024 and S2 Quire 13 vs S3 Quire 20 is 0.926, only 0.001 higher than the same comparison in Takahashi at 0.925. So this is not a large collapse of scribal structure. It is a small but real sign that section/regime can cut across scribal hand.
That is actually compatible with what I am arguing: scribal hand, section, and production weighting are separable variables. All of my modeling to this point has focused on Scribe 1. To clarify that method before looking into the <ed> heavy later scribes. The chart below shows the same point visually. That <ed> does not divide perfectly by Davis scribe, but it does separate Scribe 1 very cleanly from the later <ed>-heavy sections. And, aside from the Herbal section which has scribe 2 sheets mixed into quires with scribe 1 sheets, you can almost pick out each section by scribe and <ed> density.
