I guess it's human nature to talk about money/winrates, but for our purposes with the text, higher winrate did not mean better book. I'm curious if anyone disagrees, and if so, why.

Well, for the obvious reason - the bigger the winrate, the better the strategy, weighted by sample size. The better the strategy, the better the book. Not that it's a big deal, since Harvey Penick who probably couldn't swing a club could still give good golf advice. But as I said, the rationale is pretty obvious.
