Two events. Spaced across one year, one happened Mar 2020 and second in April 2021 (ongoing). Attendees of both failed to follow COVID protocol. Both can be considered as super-spreader events, along with many other super-spreader events (shouldn’t single them out) – I don’t think any detailed data analysis done or available on  impact of these events on the COVID infection numbers. Similarities stop there though. It is little unfair
