I tried using Sturm.  It takes longer, and there's no appreciable improvement.
I suppose I could try the macro...

Is it at all possible that the problem comes from having too many control
points?  Current count is 3338 (I'll admit this may be overkill.}  Also, the
defect seems to move upward as the incident angle increases.

Thanks for the input,
