Well, the reason for the five stars is the presentation, which is VERY solid compared to most martial arts books.. The charts and graphs are clear, althought the black clothes sometimes make it hard to see. Not for beginners .. The tecniques usually need a lot of transition to happen
Seems a good item to maximize strikes... The only thing that disapointed me is that some points are a bit vague... Without more references like "2 inches bellow collarbone" became "bellow the joint of collarbone and shoulder" Without a solid reference sometimes, it became hard to get the point..
Thinking in the past, it would be a highly treasured manual for striking some 100 or 150 years ago... Now its just as good... Just a little more care with the pictures and point descriptions would make it totally perfect... But that will surely be fixed in a second edition
