Honestly, the most important metric is deaths, and from what I can see, the SF Bay Area has done relatively well in that metric. No overcrowded hospitals, for example.
Yes, this is very important. But one should not forget also the avg. hospitalization time (which will go down once we have clear procedures for treating COVID in different stage)
* Overcrowded hospitals is what leads to large jumps in fatality rates.
* It only lags the date of infection by about a week.
* It also isn't subject to external factors like availability of tests. (Though availability of hospital beds is a factor later on)
