Why would we believe one or the other? why isn't this a standard calculation?

Different dyno types (Mustang vs. Dynojet, etc., testing conditions (high temperature, humidity, heat, altitude), and the specific cars tested (automatic vs. manual - power/drivetrain losses) all have a profound effect on dyno results.
The key that has already been mentioned is to look at a change in results for the
same car, on the
same dyno, and in roughly the
same conditions over
several dyno runs.
