ASTM E-1320 Interpretation of shrinkage

I'm in the middle of a debate concerning the interpretation of shrinkage
using ASTM Reference Radiographs. With the surrounding metal in both the production and reference radiograph
being 2.0 H&D and the shrink indication in the production film only half the size of the largest shrink in the ASTM film. My question is, if the density of the shrink on the production radiograph is somewhat darker
than that of the referenced plate, is the indication then rejectable?
