I can write us a python script to check these numbers daily. A averaging metrics across 30+ countries is a calculation that shouldn't be done manually.
I guess we both can throw our calculations, manually or with python script, to trash.
The lack of scientific justification for the corona measures
25. April 2020 Christof Kuhbandner
Why the thesis of the epidemic spread of coronavirus is based on a statistical fallacy
Practically all over the world, we are experiencing an unprecedented situation: drastic measures are being taken all over the world to combat an epidemic that is obviously looming. In Germany, for example, so many basic rights have been restricted so comprehensively and comprehensively as never before in the history of the Federal Republic of Germany.
Numerous virological experts are advising politicians. One might therefore think that the need for dramatic interventions in our basic rights is well founded by sound science. However, if you, as a scientist experienced in research methods and statistics, look at the scientific basis of what justifies the drastic measures, doubts arise.
Virtually all the measures taken are justified by the fact that they are intended to prevent an increase in the number of new infections every day, in order to counteract the alleged exponential spread of the coronavirus. For example, at a press conference on 18 March, the president of the Robert Koch Institute (RKI) projected - based on the increase in new infections observed at that time - that there would be up to 10 million infected people in Germany in two to three months if it were not possible to effectively and lastingly reduce contacts between people over a period of several weeks.
The Leopoldina - the National Academy of Sciences - formulated a similar statement in its second statement: "Although the increase in registered new infections with SARS-Cov-2 in Germany has been slowing down for a few days now, the political measures for contact restriction, which were adopted on 22 March 2020 and are valid nationwide, must remain in place". And the Federal Minister of Health, Jens Spahn, said in the ZDF Heute Journal on 19th April: "If we have managed to bring down the number of new infections together in the direction of 3,000 to 4,000 per day, then we must also succeed in staying there, only then can we gradually return to a new normality.
The actual point in time of the decrease in daily new infections
In view of the fact that all measures taken are justified by the increasing number of new infections every day, we would like to take a closer look at these figures. To do so, we will first take a look at the typical graph of the increase in new infections, as it has been presented for a long time in the dashboard of the RKI (as of April 23rd):

What you can first note..: The numbers seem to have been decreasing at least since April 3. But now we need to take a closer look. A first question is: What exactly is meant by the date in the above graphic? In this graph in the RKI dashboard, the date corresponds to the so-called reporting date - i.e. the time when the case became known to the public health department.
This is the first exciting point: It should actually be about the number of new infections per day, i.e. the time when a person became infected with the corona virus. But at the time when a case becomes known to the public health department, the person has not become newly infected. According to the RKI, an average of 5-6 days elapse between the time of infection - i.e. the actual time of the new infection - and the development of the first symptoms. As people do not go to the doctor immediately after the first symptoms, it often takes several days before a doctor is consulted who may then carry out a test, the result of which is often only available one or sometimes even two days later. The above graph therefore lags far behind the true time of the new infection.
This is exactly the reason why the RKI dashboard has a new graphic for a few days now. It shows the number of new infections per day according to the date of onset of the disease - i.e. the day on which the first symptoms were formed. The onset of the disease is currently known from 94,078 of the 145,664 cases confirmed by laboratory diagnosis. The following picture shows the chronological course of the new infections (the blue bars show the course of the new infections at the beginning of the disease):

A decrease in the daily number of new infections is therefore in reality much earlier. In order to determine the exact time, the yellow bars can be included. The yellow bars correspond to cases where the start of the disease is unknown. They are therefore still fixed at the date of notification.In order to estimate the onset of the disease, these cases can be assigned the most probable date of onset based on the cases for which the onset of the disease is known (technical term: "imputation"). In the daily situation reports of the RKI, this is done in order to better estimate the true course of new infections. Then the graph looks like this (the height of the grey bars shows the true course estimated with the help of imputation, fixed at the beginning of the illness, situation report of 22.4:)

According to this, the number of new infections per day has been decreasing since at least March 19. However, it must be remembered that the date in this graph corresponds to the time of development of the first symptoms of the disease. As already described, however, there are another 5-6 days between the time of infection - the time of the real new infection - and the time of the formation of symptoms. The above curve must therefore be shifted back in time by another 5-6 days, and so the new infections have in reality already been falling since at least 13-14 March.
