I was looking at their numbers... Sure, they flattened the curve, but they're getting the same number of deaths and hospitalizations as they did 3 weeks ago.
This virus doesn't magically disappear as quickly as it appears. It has a long decay but a fast rise. On the unmitigated rising phase, it doubles every 3-5 days. With a lockdown, the R0 is still probably close to 1 (nurse comes home to a family, supermarket is unknowingly contaminated, etc.), which means the curve could flatline for weeks or even months. So it's asymmetric.
That's why it is so awful to let the numbers get so high before locking down. That's the point from which the slow decay occurs. If you start with 100 cases, it'll decay to close to nothing in a couple weeks. Start with 100,000, and it's going to take a ****ing long time.
