At first I was happy to see a confidence interval in the plot. Then I realized the plots are based on the same numbers anybody else uses: new cases. I'm tired of people stretching the available numbers too thin. There is only so much information we can get out of them. And yes like you say I hope we will see daily sampling soon. As tests are geared up that should be easy enough. As an aside: The RKI in Germany is collecting weekly samples to track the flu. They have been testing for Corona now for eight weeks. In those tests, they found 11 positive samples out of 1089. I don't know the reliability of the tests though. The numbers are certainly too small to estimate noise after eight weeks.
