I agree with Phil. In our experience, our scores varied widley as well. One of the other competitors, with tons more experience and more than a few Grand Championships under his belt, said that with the old system if the scores were 5 and under, or something to that effect, the low scoring judge had to justify his score. In the current system there is no explanation required for low or widely varying scores.
That's how I remember it. maybe horn or bigmofo can correct me or add their recolections.
