Some thoughts to "muddy" the discussion.
Many years ago, we made leading edge templates of a wing of an undamaged
and relatively new LS sailplane. The templates were made with bondo and
cardboard in the JJ manner. We all know the root is bigger/fatter than
the tip. We would slide the root template from the root to the tip and
observe the changing shape as it neared the tip.
We then took the root template to the other wing and did the same. They
were not same. Not even very close and we found the middle of the other
wing was actually fatter than the root.
This particular LS went we very, very well. It was a winner in many
competitions.
Conclusion?
