Sure are a lot of micrometers measuring something that is cut with a
chainsaw. If you consider the maximum allowable error that is allowed for
VOR receivers and then plot that allowable error plus some safety factor you
would most likely see an obstacle that the approach designer has to
consider. It is even worse for NDBs.

Because the navaid is not on the extended runway centerline.



Nope - Look at the VOR 14 approach to ITH (Ithaca New York - Just
grabbed the book and picked that one by chance). The VOR is on the
centerline, the runwya heading is 144.6° and the VOR approach is 133°.
When
you break out, you have to turn 11.6° right to land. I don't see why they
couldn't have published it right on the 145° radial.
