Yeah, def have to take it with a grain of salt. Also, he never defined "good" in terms of a score, so it makes the tweet even less meaningful.
What I'm curious about is what percentage of people who bought FSD are "in the frenzy" right now. These are the people who knew about the button's imminent release and pushed it as soon as possible, and are now trying to go for their best score. Anecdotally, I know quite a few FSD purchasers who aren't following any of this stuff. So... it could be that most people trying will get in first round. There's just not enough info to know.
