Measuring FIM (TIR) - Two inside diameters - Conflicting readings between inspectors

Looking for the best way to measure the TIR between two inside diameters. We have the main (datum) I.D. located on a pin gage held in a precision v-block and measuring the other bore with a dial indicator attached to a height gage. We seem get conflicting readings between inspectors. Is this the best way? Would really appreciate some input.

Happy to help, but can you show us a snippet of the engineering drawing with the requirement?
