Yes, I have read it. Wether the book is worth it really depends on your style of punting. The book itself outlines a system for making money from racing. I looked at it, toyed with it for a while, it does make money, however it is not my style of punting, as it revolves around a particular type of staking in order to make the money (not sure how much detail I al allowed to go into without breaching copyright etc).

So, yes it does work (in the month or so I paper trialled it), however it will only suit certain type of punters.

And it has nothing to do under/overlays.

Hope this helps.

Cheers
