For 2022, there will be a qualification system for each sport.
My suggestions:
-Athletics - Use the IAAF rankings to determine qualifiers and limit field size to certain numbers using past participation as the standard.
-Basketball (3x3): Top 8 teams per gender (including hosts) in the FIBA Rankings
-Badminton: Top 16 teams in the rankings qualified. Limit the singles/doubles fields as well.
-Boxing: Top 12 athletes in the world rankings per event should qualify, with 16 wild cards to be awarded equally among men/women.
-Judo: Top 9 in the world rankings + 1 wild card per event.
-Diving: I don't think diving needs a system, the numbers are good enough atm. Maybe a minimum score to qualify?
-Cycling: Use a similar system as the Olympics, but adjust qualified numbers,
-Swimming: A/B Standard qualification times, invite 8 teams for each relay only. Also limit each individual event to a max 2 athletes from one country.
-Gymnastics: The number is adequate enough across both disciplines. Not sure what to suggest here.
-Triathlon: 28 athlete fields per event. 26 spots reserved for the world rankings + 2 wild cards.
-Lawn Bowls: Max 20 per event, using a world rankings/qualification event.
-Netball/Rugby sevens: Same system as in 2018.
-Weightlifting: Same system as in 2018
-Squash: Max 32 in singles draws and 16 in the doubles draws.
-Table tennis: Max 12 teams per team event. All other countries can enter a max 1 male and 1 female.
-Wrestling: Top 9 in world rankings + 1 wild card per event.
Parasports- Plan ahead and choose events which have the most representation. It was ridiculous too see many events here with just 1 or 2 medals awarded.
-If a country fails it can enter 2 track and field athletes/2 swimmers (just like the Olympics)
