The standard of technique in this book is horrendous, if the author cannot perform the kata in the most basic form, how can you trust his applications or knowledge of the system. Very poor content. Understanding of real-world self-defence for this man is obviously at a zero. Nonsensical waste of time. Even his stances, which are not stills from a performance, they're clearly posed, are a joke. It looks as if hes about to keel over. Don't know where he bought his black belt but I hope he kept the receipt. Avoid like the plague.
