When the angle is close to 180 degrees the calculation becomes inaccurate.
I have made a control section at one triangle. And the values are different. A new version of NGON needed to correct this?

I have calculated the deviation for the angles regarding this geometry. It turned out the deviation is always high when the angle is close to 180 degrees.
