While a simple solution for a popularity contest, it has great drawbacks when looking for techique comparison. Someone’s family may be bigger or louder than others, some people may have more fans in the audience, who can afford to attend will skew the vote, being an international event would mean that it’s likely the home team has the advantage as people from the host country have a greater opportunity to attend, some event crowds may be determined by time of day or by public transportation, and the audience may not see the whole (5 hour breakdancing) event and certainly won’t see the performers as well/as close as the judges would. Additionally the audience has so many new viewers during the Olympics that don’t know how hard certain moves/sequence of moves are while some easy flashy moves will wow a crowd every single time. None of those things show particularly compelling qualification to determine how technically good the performer/performance is.
She talks about laughing on some podcast but I can’t remember which one. Anyway, she said that most comics don’t really haha/laugh out loud at great jokes, but will simply say that’s a great joke with approval. So being the host on tv she is having to train herself to laugh at loud at things. The show is scripted and the footage cut up post filming so some people/contestants are funnier but they couldn’t air it or their words were tempered by the writers/editors. Here’s one interview podcast with her and Conan https://youtu.be/qDkFXrS-P-8?si=t9MqFHltXbSm0ccG
