- A Netflix weekly top ten is not ten titles. One show has held seven of the places.
Sat Aug 08 — Across 493,600 country-chart rows, 18,586 weekly lists put one title in two or more places. Seasons explain 26,068 of the 26,093 extra rows. The 25 that are left are two different films sharing one name inside a single top ten.
- Fourteen distinct ways of being wrong. Ten of them now fail the build; four do not.
Sat Aug 08 — We tagged every changed figure with the kind of mistake that produced it. One kind accounts for eight of the thirty-three. Four kinds still have no test, and this piece names them rather than reporting the coverage.
- Three in five Korean film titles share their name with a foreign work. For series it is one in four.
Sat Aug 08 — We asked Wikidata which countries made something with each of our 397 chart titles. Films come back ambiguous 58.1% of the time, series 23.6%. Short names are the reason, and Korean films get short names — but that is not the whole gap.
- We said we could not count the acts our K-pop panel misses. We can, and it is 1,312 groups.
Sat Aug 08 — Wikidata holds 2,128 Korean musical groups. Our attention panel sees the 816 with an English Wikipedia article. Among singers the gap is wider — 5,408 exist, we measure 1,421, and 3,572 of the missing ones have a Korean article.
- Everything we can say about Korean casting rests on a median of five recorded names per title
Sat Aug 08 — Wikidata records no cast at all for 266 of 901 Korean titles. Of the 635 that have any, the median series lists five people and the median film four. Here is what that does to every figure we publish from it.
- Half the titles in our Southeast Asia panel cannot be verified as Korean. Here is exactly how big that is.
Fri Aug 07 — 214 of 421 titles never reached a global Top 10, so Netflix's language label — the only thing that separates a Korean work from a foreign one with the same name — cannot be applied to them. They are also the small ones.
- One flaw in how we matched titles put wrong figures on seven pages and four articles in a single morning
Fri Aug 07 — Our Korean Netflix catalogue was 294 titles and 27.7 billion hours. It is 236 and 23.7 billion. Here is the mistake, how it spread, why counting alone would never have caught it, and what we changed so it cannot happen the same way twice.
