I was going to suggest something like that - use a common reference.
When you say "shows it" are you talking about a meter indication or how
far the waveform graphic goes toward the limits? A recording at -6 dBFS
only fills up half the waveform space and that's pretty obvious.

I think it would be interesting to figure out what's going on so you
know know how to interpret the meter readings on whatever program you
happen to be recording on (that's really the only time you need to
worry about it) but I also don't think you should agonize over it.
What's best for your client is that he knows that he's not going to try
to overdrive the A/D converters, or, equally important, clip the mic
preamp or analog side of the A/D converter.

You should check your drivers and their control panels carefully. It's
possible that there's some digital attenuation set on the input that
you didn't realize. That could explain everything.
