I think the bigger problem is exponentials, rates of change, and control systems. Right now, we lock down when numbers get high, and open up when numbers get low. There's about a month lag between actions and hopsitalizations, so we act on month-old data. We don't look at rates-of-growth. This results in a roller-coaster. We ought to take whatever measures we need to keep R0<1.
