Christian-albrechts-universitaet's three-year grant acceleration

Christian-Albrechts-Universitaet zu Kiel shows 7 grants in 2022–2024 against only 10 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
