So I linked to one important source I used in my non-professional but (hopefully) mathematically literate guesswork about how COVID-19 deaths in the US will increase over the next while. What I didn’t appreciate at that time was that the graphic that they used to discuss geometric growth in deaths in various countries is a dynamic graphic. Every time a country updates its total deaths on its own official websites, which happens once a day or more for Eurpoean and North American countries, the graphic itself updates. This means you can’t click on the link from a past article (or in this paragraph) and get easy access to the numbers I used when writing a particular blog post.
