My understanding of a lot of countries approaches is that they're not trying to minimise the total number of people that have or will be infected, but they're trying to minimise the maximum number of people infected at a time (to ensure that healthcare is still available to everybody that needs it). In these simulations, that would correspond to drawing some horizontal line across the chart and trying to keep the orange under there the whole time.

I'm not sure if the long-term outlook is "we're all going to get it" like the flu, or we're trying to stave as much of it off before a vaccine is widely available.
