Performance Gauge readings

I have searched this site, and the web, and I have yet to find any good information on the Mopar Performance Gauge readings. I would like to think it was more than just a “neat” gauge.

Is there a table or chart somewhere that interprets the Performance Gauge?
Man, you really threw a screwball to the masses with this question.......
