reported dimensions change for TP

[Jonathan S]

Explain this! As you can see, I reported the X and Y location of CIR2, then reported the true position of CIR2 in the X and Y axes to CIR1, but the reported X and Y have changed. How can this be? I was aligned to CIR1 in the X and Y already when I reported CIR2 the first time, so measured X and Y relative to CIR1 in the true position should be the same.
