Okay, to elaborate on my comment above; I think you're confusing 'move' and 'sequence'.
Certainly, a route which consisted entirely of movement between unstable positions, which had no rest points, would be very difficult (I wouldn't call it perfect
per se), but I would say it was one long sequence, not one move.
It might be better to define a move is the bit between two metastable* positions, and use your definition as that of a sequence.
This doesn't really provide a useful definition of a move, but as there are so many different kinds of move to make, can we really come up with one?
*By metastable, I mean a position which is stable temporarily, but uses too much static muscle power or puts the body in too strange a position to be a useful rest - you must move on, or you will get tired and fall off.
