eyrie,

I don't know, with thousands of techniqe studies in our repetiore, all of which work, it's enough to keep one busy. Of course having a surgeon in our program for a long time, I've learned not to worry about what I'm not trained to deal with, such as medical knowledge.

If the technique works, does the why, if you can really explain it, really matter?

BTW, from long experience it's enough to learn how to make do correctly.

I guess the difference is whether undersanding the underlying reason a technique works is more important than the study of the infinite ways techniques can be used effectively.
