A lot of FReepers don’t seem to understand the very complex logistics of cranking out tens of millions of tests.
Validating them all to be reasonably accurate adds a whole nother layer of complexity.
My concern is how broad is the test? Is it picking up "something" causing all these positives or are machines defective, not calibrated properly.
Suggest that the same group be tested 6 hours later with a different type machine and "educated" testers.
