I think that the point is being missed. I do not disagree that there is a
discrepancy wrt "who" did the work. The key point is that the Board
Certified Physicist signed the calibration report and therefore took
complete responsibility for all of the work performed by Frank. .... the
construction of the phantom and the writing of the algolrithm, etc. If the
Board Certified Physicist did not independetly validate the results
calculated by the computer code and also the construction, composition, etc
of the phantom the Board Certified Physicist has placed him/herself in an
"soft" position if there is an error in the calibration.
