Hah, everything's relative

I was suggesting using existing material (rather than something that has just arrived) - if known-good material can be messed up or changed up by subjecting it to a ziplock and a fridge or temperature fluctuations for a couple of weeks, that would suggest it's the transportation process that is causing the issue (though I suspect it isn't).
If it stays pretty much the same, it points more toward something else, like (for example) storage-related volatiles airing out.
What you're talking about kinda-sorta verifies the need to acclimate in the first place, but I don't think anyone would dispute that after being in the hobby for a while.
