I'm confused as to what you mean? Cases are recorded through positive tests sent to the CDC. (maybe after going to the white house first? I can't remember if they stopped doing that or not).
Testing requirements vary from state to state, but that's how cases are detected and how they derive the numbers.
I mean, if tests are done by random sampling, contact tracing, or by mass testing a la Chinese cities, then you get a whole lot of asymptomatics registering as cases. If you only test when people present at hospital, you get only the worst cases.
Depends how the cases were detected—but yeah the 0.4% was being optimistic.

Yes, but the west outside of a handful of studies only tests when people show symptoms and don't do mass testing on any scale.
