My understanding of the matter is that:
Where the piezo and c.u.p. (l.u.p. for low pressure rounds) expansion measurements are taken from the same point on the cartridge case, it is possible to extrapolate data;
BUT,
Where the measurements are taken from different points, which apparently is the case with at least one testing regime in the U.S.A., data cannot be extrapolated.
It is also my understanding that the C.I.P., which operates under the supervision of the Belgian Parliament, kept everything the same except for the change from lead/copper slugs to piezo sensors.
