It makes a difference in the absolute numbers, but it doesn't really matter for the trends, since each country's testing policy is relatively consistent with itself. In other words, the graph shapes & trends are stil comparable, whether a country's testing captures 1%, 10% or 100% of its cases.
- jacquesm 7y agoIn some countries it will even matter for the trends. There are some countries that actively cook the numbers to make their politicians look good, and where there are very sudden kinks in the graphs you can be sure that the whole story hasn't been told. As or the testing capacity, that's a big factor too and it is non-linear in many places: testing criteria are changed based on how much stock there is of test materials and how much capacity on the machinery. The closer to capacity, the stricter the criteria.

- bagacrap 7y agoThe testing policy in most countries is to increase the number of tests over time. How is that consistent? consistent would be testing a random sample of size n every day without changing n.
