Alar in the comments has already tried to clarify these:
- AA World Cup applies only to 2020, not 2018-2020
- Stuttgart 2019 Worlds All-Around is CI, not CII
- More than 12 or 20 will qualify through Stuttgart CI All-Around to make up for spaces left from Apparatus Finals that don’t have 3 finalists NOT from the top 12 teams
These charts are somewhat clearer than the most recent FIG videos.
