Interesting to note that none of the waveforms in the article cited are
the traditional "plus" display.

The plus display comes from taking the mark filter and putting it on the
"x" axis, and the space filter on "y" and looking at the picture.

Since the mark filter and space filter are in the demodulator, and as
someone else observed really speak to how closely you're tuned to the
received signal, that just doesn't seem useful.

The spectrum graphs might be.
