This is interesting...
In this case, LDPE calculates the wrong angle, but nevertheless, I would split this quad into two triangles ;)
I doubt that I am able to correct this to clone the exact behaviour of LDDP or Datheader.
I tried a few things to change the angle calculation, but none of them gave me "better" results.
As long as LDPE does not allow values above the specification limit I might be free to leave it as it is.
Numerics..., what else could I say... :D
