I don't have the energy to look up the post from Tracy, but I'm pretty sure it's exactly the opposite of what you're saying. QSC's realized the folly of not changing caps between batches, which got them fucked with the 4mg/10mg debacle. I understood that they are now going to change colors between batches.
They also mentioned tracking batches, but without a label, I don't know exactly how that'd be done, maybe mark the carton with something?
Anyway, it sounds like someone needs to look into testing this new gold/clear.
