There’s much discussion in Glasgow regarding WHO will compete … aside from Teams 9-16.
NATIONS qualify for those positions. Trinidad and Tobaggo, for example, has two strong WAG gymnasts: Thema Williams & Marisa Dick.
It will be up to that nation to decide whom to send to Rio.
Note: The Olympic Committee in some nations decide NOT to send gymnast invited by FIG. Some don’t want to spend the money. Some have performance requirements. “Athlete must have proven potential to finish in the top 50% of the field at Test Meet“, for example.
