Domestic copies claim over time and staleness, June 2013 to April 2019

What this is

The 2013.6 mook gives an upper bound on the 10M date, so the 10M-to-12M window has a minimum, not a maximum: 30 June 2013 to 5 June 2015 = 705 days.

The values

• June 2013: >=10,000,000 (1000万部達成, mook blurb)
• 31 March 2017: >12,000,000
• 29 April 2019: >12,000,000 (vols 1-53)
• Static span days: 1,424
• Per volume 2015: >222,222 to >230,769 (12,000,000 / 54 or / 52)

Some detail is too fine to show here; it is kept in the trainer’s notes.
