Has anyone have a list of brass (by lot) that they have analyzed in one area they lived in them moved and have those codes be different with the same lot of brass? Across the board?!

Is this a 1 to 1 comparison of codes? I mean are you asking if someone has a lot of, for example 2x fired brass, then they move and they retest and find the same 2x fired brass has a vastly different code? I ask because you could theoretically burn 100 pieces of once fired brass of the same lot testing, and come up with a dozen codes. Your code may also change slightly over the life and firings of the brass.

Yes
Have a set of codes for a large lot of brass in one area of living at then move and have that same lot give a very different code at the new residence

Assuming all have the same number of firings, you can still have a wide variation in a big lot. Do you go through, chose a representative case after each firing and burn it? Or are you comparing a code from 1x brass to 3x? Did you pull a representative case to burn each time? I ask because I'm genuinely curious. I've seen on other forums where people have questioned the efficacy of the AMP simply because they burned more than one case and got a different aztec code.
I know whichever case you burn is supposed to be the most representative of the lot, meaning you either meticulously ball mic the whole lot after the first firing and then weight sort them and then figure out which case weight and neck thickness you have the most of, or you do a random sample of some percentage and accept the code it gives. I know I have cases that started out at 0151 on their first firing that are now 0159 on their 3rd, and I do a 20% random sample of those 300 cases to find the most representative cases. Those cases are on the 7th firing and I haven't done another sampling.
It makes me wonder also, if by moving to a different power grid, if maybe the machine has to change the parameters based on supplied power. Maybe your mind is kind of in the same place...since the power grid too, has a tolerance of supplied voltage and Hz frequency. Apologies, it is an interesting question and I have an inquisitive mind.

This is what I think the biggest issue is

Can we say the specifics of the code result change as an example?
Were the AZTEC cases used to generate the later codes the same weight and were the necks altered compared to the baseline?
