In testing I found it is not possible to export G7 calibration measurements and then bring them back in for a new calibration. It fiscally can be done but the output is way off. Something must be missing in exporting or loading the measurement in the new calibration dialog.

So I guess if I want to try G7 calibration with the ES-2000 and then use the FWA and create a profile on top of that I would at least have to do the initial G7 calibration with 1 copy.
