This study in Georgia sheds some light on the so-called superspreading events. (distinguished from superspreaders; as I understand it, Mardi Gras might be a superspreading event)
The study finds that 2% of the cases appear to cause 20% of the new infections. (and, I would expect, conversely, 98% of the cases cause 80% of the new infections). (Btw, notice that statement is not about superspreading events, but superspreaders.)
Characterizing superspreading events and age-specific infectiousness of SARS-CoV-2 transmission in Georgia, USA
I've not gotten through this yet, so maybe I'll have more to say. It does have information about R before and after shelter-in-place.
IMO, superspreading at events is more about policy (allowing the events) and individual behavior (cautious vs it-doesn't-exist and everything in between), than about the disease itself.
