FYI, just had the following response from the IMGA re my enquiry re expanding the archery to 600 competitors:
Thank you for your comments and inquiry.
Due to the Covid-19 situation there has been no progress yet in the discussion on this matter.
Now the new dates have been set and everything is being prepared for opening registrations later this year.
We are aware of this issue and it is addressed by the World Archery federation together with the Organising Committee of Kansai 2021.
When we have more news on this subject, we will surely communicate as soon as possible.
