Bryan,
Your test results are right on the money. Whoever told you to set it at 4.5 kHz was referring to the max deviation of the TX. This is the level that you set the IDC or clipper to (not sure what it is called in the MASTR III). 4.5 is a good level and will prevent the deviation from "overshooting" the 5 kHZ max.
