2/ This morning I added a flag field which asks "is today's 6 day average GROWTH RATE smaller than yesterday's ?" Ideally we want to see each day's growth rate as smaller than the day before - that way lies extinguishment.

3/ The good news is that the VAST MAJORITY of days display that characteristic. The bad news is that as times goes on, more and more days fail that characteristic. If deaths is the data, growth rate is the first derivative, and growth of growth rate is the second derivative.pic.twitter.com/VBjaGjP5LE

4/ Second derivative is still good ... but third derivative is not so good. Will be interesting to see where this goes. My prediction is that within 2 weeks we're going to see more days than not fail this test.

5/ To be clear, all of this is not a "model". Models aren't just curve fitting and tweaking params and saying "Eureka! I understand it". This is just playing with data, trying to get a handle on what the derivatives look like. Also: my thoughts are worth what you pay for them
