COVID-19 progress?

It’s an excellent start.

The obvious question: how many days from peak to most recent? (Parallel question: what improvement was each country showing at the point which is the least from peak? If, for instance, the U.K. has only been “improving” for 20 days, where was everyone else at peak+20?)

The follow-up is whether “most recent” is also “lowest since peak.” (Shorter: Is the derivative negative or positive?) A bit of noise is one thing, but if a country is starting to trend upward again, that’s another question.
