I love these plots - so useful for setting strategy in a few days!
I'm honestly shocked that the curves are so even for so many years, and so many varied games. Logomotion seems to be the season with the least "unequal performance", but they're all pretty close. That tells me you only have to beat the average score by 1 standard deviation to outperform 90% of teams. That's way more skewed than your typical normal distribution.
