So did the testing methodology change? Maybe I missed this in the doc, and I am just blind but something doesn't make sense here.

Let's take the numbers they provided at face value, there was a spike and then a decline even as testing was ramping up, before the new waves of positive.

So what changed? If the testing was equally as flawed the entire time, we should have never seen a decline in cases, if anything we should have only continued to see a rise, but we clearly saw waves and corresponding hospitalizations during the same periods that have mapped proportionally.

So what am I missing here?
