I checked the ODG (Objective Difference Grade) scores for a few reference vectors using the PQEvalAudio Tool and found that some of them show ODG scores as high as -3.5

If we look at the range as described in the link below, it looks unacceptable.

Am I missing something or are these scores valid?

Thanks and Regards,
