How it’s built
- Took Dengeki Online’s weekly sales chart: 499,753 Sword, 347,629 Shield and 254,612 Double Packs, 1.10 million boxes in all.
- Counted each Double Pack as two copies, giving 1.36 million copies, matching Dengeki’s headline.
- Divided: Double Packs 23.1% of boxes; their copies 37.5% of all copies; second copies 18.8%.
What we assumed
- Dengeki’s chart counts are accurate.Its per-version rows reconcile exactly with its own totals; the research has no other source for this split.
Sanity check
It covers boxed sales in Japan in a single launch week, when committed fans who buy both versions cluster. Later weeks and other countries are likely lower.
