saw you already finished the material but thought I’d share that for knowledge’ sake. I imagine the difference in COAs is because of the very wide testing parameters labs are able to use since there is no national standard, or even state standard in most states. It’s sad to say but more than enough labs have been found to skew results toward a satisfactory COA for the customer. It’s not like they’re outright lying, but of course as a business, with the wide variety of testing parameters available for their use, would they choose the most accurate parameters if it were losing them business?
