A Kiel University project counting colophons in German-language medieval manuscripts finds roughly 1-in-5 frequency, not Kwakkel's 1-in-7

A DFG-funded research project at Kiel University's Institute of German Studies, "Colophons in German-language manuscripts of the Middle Ages" (led by JProf. Dr. Margit Dahm, first phase 2021–2024, extended through 2027), is a genuine denominator-based corpus count of colophon frequency — the kind of study that could in principle test Erik Kwakkel's "about one in seven" figure. The project's own page states: "around 11,000 manuscripts from the 12th-15th centuries from a total of 29 libraries... were analysed for their colophons... So far, around 2,200 manuscripts with a total of over 3,400 colophons have been identified." 2,200 of 11,000 is approximately 20%, or roughly 1 in 5 — a higher rate than Kwakkel's ~14% (1 in 7). But the population differs: this project covers German-language manuscripts specifically, a narrower and linguistically distinct set from the general Western Latin/Dutch material Kwakkel's career centers on, and neither the project description nor Kwakkel's own writing draws any connection between the two figures. See question-verify-kwakkel-one-in-seven-colophon-figure-against-a-corpus for the open question this bears on.
