I understand, yes. Although I had never thought about it quite like that before. I usually look for the most comfortable way of playing, and usually this works out to appear the smaller motion.
But with regard to this scale business...
I really wish I could demostrate what I mean on this one, as its so difficult to explain in words. Basically, Im playing the scale using little more than weight of my arm plus rotation of the forearm / wrist. This seems comfortable, and appears economical. I use the TO technique to move between position.
When using 123/1234, a pivot is required (as you mentioned) to reach black notes with '4'. I find this not only more effort, but also far less aesthetically pleasing. It seems like an unnecessary movement to me - its far easier to simply alter the fingering slightly and have the scale fit the hand perfectly. Infact, I have altered the fingering on several tricky scale runs - guess what, they arent tricky anymore!
Or maybe my hands are just deformed?

I have no idea.
The reason I even ask this question, is that Im unsure whether this method may prove to limit my technical capabilities in the long run. At the moment Im still a student, and forging my technical preferences. Funnily enough, I use this pivot motion in arpeggios all the time. But it seems completely unnecessary in scales - I dont see any reason for such a significant motion.
Not saying the entire piano world is wrong - I just havent discovered yet the benefits of this fingering (quite the opposite infact).
