Notes for the methodologically curious. Shares and multiples use recency weighting (people who came of age recently count more, per the era pills) and shrinkage: each school gets 20 virtual alumni at national rates, so a school with 4 noted alumni can't post a 200× multiple. High-school data on Wikidata is far sparser than college data — a missing trait usually means Wikipedia editors didn't record it, not that no alumnus has it.
