Price's Law suggests that the square root of the number of workers in a particular domain constitute half the productivity. This means if a particular office has 100 coders, 10 of them make up half the total productivity. So the top performers are doing ~5% of the total work each, while the regular performers, on average, are doing 0.5%. So statistically every place with 100 developers has ten 10x coders whether that's Google or anywhere else.
