Fink's book helpful???

[Spatula]

I borrowed this book " Mastering Piano Technique" by Seymour Fink and I've just started to read it.  It really gets indepth with how muscles move and coordinate with the mind, but at the end, how much really does this help you?   I want to invest my time into this, but at the same time to make sure I get a good return in terms of piano skill and enjoyment.  So for those who have read this, please reply!
