Yup I wasn't knocking the usefulness of the book with regard to the win rates. Unfortunately I think the advice given in the book is sound.
I was questioning the usefulness of the set of win rates included, given the broad range of data included.

I'm always interested in win-rates as they reflect the ever changing nature of the game. For example my own win-rates seem to be inversely proportional to the number of players at the table, and I suspect this is the same for many short handed players.
