Nope. I just looked at the wear arc on a pin from a worn chain. (Okay, I'm weird. I keep my pins and pieces bagged together for/with each chain.) It is approximately
180°. Wear difference would thus be 16/180, or 9% max.
Meanwhile, the sprocket teeth - which you can't flip - continue to wear.
And we haven't accounted for
other wear mechanisms, such as high chain angles, vibration, etc...
