Sorry for the delay, I've been kind of lazy here.

• It’s obvious I am not making myself clear. I’ll just add a few words one more time. Cutoff cycles and ‘positive CT’ (if CT is equal or lower, the test is positive, if CT is higher, it’s too weak and the test is negative) are calibrated using known samples. To get approved, a given test array goes through several verifications, by different countries obviously. And once that is done, these values cannot change, so like I said, no manipulation.
• It was one of the ‘expert’ consultant doctors on one of these channels who grossly misinterpreted a CDC document about breakthrough cases (the infamous “CT lower than 28”). I even commented about it on some Hive posts months ago. After that, everybody and their mother was talking about how the CDC kept changing the CT (in particular the Canadian lawyer who had several suits against the Canadian government and kept spreading other debunked lies), which is not true at all (they were just looking for breakthrough cases with high viral load). It was very clear he completely misread the document. In my opinion, as he was a doctor, the misunderstanding was on purpose. But that is right, I cannot prove that.
• The entire Chromosome 8 sequence contains over 145 million bases, so yeah, you can say it’s an extremely partial match.
