There seems to be a very well defined separation between those who have a relatively high chance of becoming critically ill, and those who have a very low chance. Depending on what you are optimizing for it could be more important to keep those groups separated. I wonder if having known that for weeks now has lead to better social distancing between those groups, even if interactions within the low risk group has stayed rather high. Could lead to a lot of spread with very little detection because we largely only test for and catch the really bad cases.
