Seems to show a bit more than just the usual rich/lean situations, also goes through timing as well as plug heat ranges.

A good read.

Was quite accurate too.
My timing was 1 degree out, and was running a little rich at idle.

The only gripe i had with it was the desciption of timing.
too much timing = too much advance
too little timing = retarded too much.
