Yesterday afternoon. I was in the middle of turning that last Stanford talk into an essay. This was one of the points. During the talk I said this was important enough to be a separate essay, so I wrote one.

To me, it seems muddled; I don't see the usual thanks to the usual suspects so I assume PG single-foundered it instead of running it past RTFM et al.

If you can point out a specific muddle I can fix, let me know.

"if the difference between the 20th and 21st best players is less than the measurement error, you've still done that optimally."

I thought that the coach was responsible for minimizing the measurement error. Then, the best he could do is to pick the best team. How do you define measurement?
