I wonder how much of this correlation is from the publishers as opposed to interaction between writers who would wind up comparable in present day status.
Breaking it down further it brings to mind mapping with more data than we probably have. Like say if they found "muse correlations" with everyone - mapping productivity and interactions. Like say being in the Shelley's social circle was associated with a 5.0 but the one copy writer of no historical note has a 4.5. Of course if someone was prolific enough they might cause anyone who interacts with them to have a high number as a sheer mathematical side effect.
