I have owned this book and the accompanying video since they were first published, and worked through all the movements he describes for myself and with students. While Prof. Fink has done admirable research into the anatomy and uses of the pianist's mechanism, the exercises and suggested movements he puts forth reveal an irresponsible, if not dangerous, lack of differentiation between efficient and inefficient motion at the keyboard. There is no commentary on what the effects are, for example, of abducting and adducting the hands at the wrist joint to the extremes of their range-of-motion. It's called tendonitis.
The array of primary movements in the opening chapters have nothing to do with actually solving musical/technical problems,
and there is a disturbing contradiction in his advice on the use of isometrics.
There is no analysis of which parts of our bodies are best geared for fast, effortless motion at the keyboard--indeed, nowhere does he state what a free, unfettered, coordinated technique should look and feel like.
He falls back upon the old cop-out that "there are many correct ways to play," as if we are creatures built with an infinite variety of differently-working muscular and skeletal structures. We all have the same basic structures, which obey the kinetic dictates of their makeup.
What is most unsettling, though, is the explanation of hand/finger positions on pp. 36 and 37. All three positions pictured are at best fatiguing and at worst dangerous when applied to playing--especially fast passagework.

Also, the use of the thumb in scale playing as explained on p. 115 "passed-under and prepared...pronate arms and abduct hands..." is very dangerous and, if one follows his direction to "ingrain" this motion, will cause injuries.
There are too many other problems and inconsistencies in the book to list, but the best summary I can make is that it presents information without evaluating it, and lulls students into thinking that none of these motions will hurt them. Instead of "rest(ing) at the onset of fatigue or tension," (p.115) one must realize that fatigue and tension are signs that something is wrong. The goal of technical training should be to create comfort and freedom without compromising the music, not to force a bunch of unnatural movements into our bodies.
The best book on technique isn't out yet, but it's by Dorothy Taubman. Look for it.
