Grasshopper Mesh Point Normal Glitch

I could very well just be using it wrong but I’ve run into what appears to be a glitch with the Mesh Closest Point + Mesh Eval components.

I cant work out a pattern or reason. My normals on the planar mesh should all be the same as its flat but i get a few odd numbers. If you move those broken points around they sometimes ‘come good’ again but I don’t understand why.

If anyone can solve my confusion I would be extremely appreciative.

If you triangulate your initial quad mesh to tri-mesh, then you’ll likely get a more reliable result.
