I feel like no two turns ever have the same foot width.
What skis I'm on also has an impact. Not sure why but skiing with my feet rather close together makes my big daddys perform better but my legend pros are the opposite - if I want to really take charge of those puppies I go wider into more of a race-like stance.
I would say my average stance width is very close to my "pee width" though
I agree that different skis will need different stance widths, but what I mean by consistent
is consistent throughout the phases of the turn.
The major way that is visible is by watching the ski boots at the different phases of the turn. What you don't want to have happen is increased width at the intitiation of the turn followed by decreased width at the completion.
As far as varying stance width from one turn to another, I don't think that it is allowable "instructor" technique, but if it works for you then no worries!
One concern I would have is that if it's not your choice of changing stance width, rather it happens naturally, then that could be an indicator of ineffective edging movements or equipment concerns.
