I am doing mag calibration according to AN5019 Rev 2.0, Section 5. Seven Parameter Model

I cannot really understand the content in page 22. 

About |A| says

Can you give me more information about this paragraph? what if we assume that attenuation is 40% or 60%? Does it make any change on computing?? Can we make |A|=10 as we want??
what knowledge should I have before I can understand these?? please let me know it.
Thank you very much
