Hi Alessandro,
The smoothed polygon does not actually pass through the vertices.
I suggest that you start the polygon on the middle of the bottom edge
and maybe add another vertex on the middle of the top edge, even though
the polygon is flat there (or to be even more symmetric add a few
vertices along the
bottom and top edges.

Thanks Bill, that was really helpful.
Actually I've another question about the smoothed-polygon mapping. I
usually create them with a routine similar to the following one:
***********************************
smoothedPolygon
vertices
5
0. -0.025
1.0 -0.025
1.0 0.025
0. 0.025
0. -0.025
n-dist
fixed normal distance
-1.0
lines
250,150
boundary conditions
-1, -1, 1, 0
n-stretch
2. 10. 0.00001
exit
***********************************
and I think that the leading edge should be in the origin. Is that so,
or the smooth function makes the mapping a bit "longer" and it is
somehow shifted?
I do appreciate your help,
Alessandro
