β€œImagine you are analyzing a school's performance on standardized tests. You find that 80% of the overall score improvement comes from 20% of the students. If the 80/20 principle is fractal, what might you expect to find when you analyze the performance of *just* that top 20% of students? Give a specific example. Consider a sports team where 80% of the points scored come from 20% of the players. If the 80/20 principle is fractal, what might you expect to see when you analyze the performance of *just* that top 20% of players during practice? Give a specific example.”
