Peter, I see that in fact you weren't referring to the base levels of the receiver tones as compared to the disc tones. If this is the same over a number of trials and isn't simply measurement error between one receiver tone try vs one disc tone try, then it's curious. The adjustments to the various speakers should be essentially the same, regardless of the source of the test tones.
