Daniela Mercury

A survey by a USP professor shows that Daniela Mercury's Pipoca da Rainha block drew about 20,000 people at its peak, not the 2 million claimed by organizers. The study also estimates 21,000 attendees at Michel Teló's Sertanejinho, versus 1 million reported. The analysis employs advanced technology to challenge hyperbolic crowd figures common in mass events.
