Tympanometry question for audiologists

Can somebody tell me what the scale on some of the older tympanometry graphs
represents? I learned and am used to graphing tympanometry as a function of of
pressure vs. static compliance. However I am now faced with graphing it as a
function of compliance vs. pressure on a scale of 10-0 ( with 10 being very
little or no compliance and 0 being max compliance). The thing I cannot figure
out is where do I get the figure from 10-0? I am using an automatic
Grason-Stradler which only graphs it as a function of static compliance on the
screen and no where does it give me a value like that. Even Audiometrics could
not tell me where to get that measure. None of the books that I had in school
do either - I looked in Kats. I have been told that it is just a relative
measure and to draw it in based upon my static compliance measures - I don't
like that answer (even if it ends up being the case). Does somebody have an
answer for my ignorance?
Thanks in advance!
