Thats because I forgot to measure it :(

Hey so did I :) AFAICT you only calculate axial modes?
I started one in C that calulates oblique and tangential too, but I can't
figure out a sensible way to display the results. The problem is that the
ideal result is a curve.
I will work on it some more soon, and see if I can get it to graph the
difference between the ideal and actual.
