  2. 3% growth in DC from 4.21 to 4.22 is the lowest so far. Two weeks now of less than 8% growth each day. let's hope that we approach 1% by May 1.

    1. Need to also see a corresponding drop in total new cases also. Concern is that being stuck ~800 could be simply a function of the testing capacity. Obviously as you add more cases, the denominator will rise and hence the % rate will fall, but if there are untested positives out there, it doesn't do the region much good.

      Ideally I think you'd want increased testing and decreased total cases. And I haven't looked at testing capacity yet (maybe someone else can?).
