What this is
The official series are and (TPC, Japan, B inputs); the rosters are, and (Limitless, C, mostly Western, earlier bases for NAIC/EUIC). Assumptions: gym events and seats move with the number of people playing; Japan and the West grew alike.
Where it comes from
Our calculation from other figures in the trainer’s notes:
- EstimateEvents held at Pokémon Card Gym stores, Japan: 2019 against the March 2020 plan against the year to May 2026 (one basis: sanctioned gym events; events, not players), 2019; March 2020; year to May 2026
- ReportedSeats in the adult (Masters) division of TPC's Tokyo Champions League card tournament
- EstimateThe size of Pokémon card Regional championships in the West, by season1,912
- EstimateCard game International Championship entrants, North America (NAIC; NAIC 2017 is 'NAIC' Indianapolis), 2017-2026 (no 2020-21)
- EstimateCard game International Championship entrants, Europe (EUIC), 2016-17 to 2026
