This seems deliberately obtuse, you're admitting to fault in the brewing process but rejecting the possibility that the raws may be less pure than you advertise. Almost all testing of EQ raws over the past several months have had results in the realm of 75-90% purity, with only Chinese testing showing 99%+ purity. Do you think its a coincidence that your finished EQ results are so far off the mark?
Brewing is really very simple math at the end of the day, if you really want us to believe that your brewer is so incredibly incapable that they cannot simply weigh the correct amount of a compound, that's fine, we can go with that. But it would serve you better to perhaps be a bit more open-minded.
You have this mountain of evidence to suggest your in-house testing of raws is not accurate, yet you'd sooner just lay all blame elsewhere. This kind of attitude will not serve to fix your problems in the future.
This is a great attitude but you might consider that if your products were accurately dosed people would pay exponentially more for them. $7 for 20% underdosed product will net you some sales but you might have twice as much business selling accurately dosed vials for $15. I'm sure you can do the math on how it scales - just don't use your in-house calculators. I recommend a trusty TI-84.
