What this is
Cumulative claim / volumes covered. The same 12M figure appears in a 2017 encyclopedia entry and the 2019 publisher release, so the publisher did not update it across at least ~10 volumes (C inference).
The values
- Domestic cumulative: >12,000,000
- Volumes: 53
- Per volume avg: >226,000
Some detail is too fine to show here; it is kept in the trainer’s notes.
