What is the uncertainty of your RoC estimation?

One measurement of the ETMY ROC was 57.6m, but we trust another measured value of 60.26m than the other.
The value is always dependent on the spotposition on the mirror and how the ROC is calculated from the mirror phase map (e.g. spotsize, averaging method).
So I don't think this is a huge deviation from the spec.
