Wow, that graph is incredibly illustrative. I played with the settings to see what would happen. A massive difference of when and how high the peak will be with the length of time for mitigation efforts. 15 days is a disaster, 60 days works pretty well, but moved the peak to June 27. And RO was dramatic, in other words how many people will an infected person transmit the virus to. When I make a guess at where we are now with the other parameters including 60 days of mitigation efforts and the RO is 2 we have 2,800 deaths. When the RO is moved to 3 there are nearly a million deaths. The real world estimates are between 2 and 5, because we don't have enough testing to know what that number is.
