Week ending 20 September we had less than twice the testing (of the average of that three), but approximately 8x the cases (of the average of that three).
By your reasoning, we should only have 2x the cases? what about the other 6x?
People generally only get tested as they're infected, because they've been near someone infected, or they're in a country that is heavily infected.
Denying the excessively heavy infection here, because we do more tests, is telling about 10% of the story.
If we tested nobody would we have no infection?
