I really wish they’d start reporting those things in independently verifiable forms to the maximum extent possible. Spreadsheets, Jupyter notebooks, etc.
All the information needed to derive the # as well as why its provisional and they can't provide a "Jupyter notebook, etc." right now is right there, in the article.
Are you talking about something two or three links deep branching out from the article? I don’t see any language even suggesting there’s such data to navigate to that’s specifically related to the article’s subject. There are three links in the article that seem to link to some procedural background stuff they thought offered good context to what was being discussed. What information specifically in the article did you feel satisfied the ability to derive on the spot?
