 Thanks for the pointer to Financial Times, especially the graphs with lines for "doubling in 1 day", "doubling in 3 days", etc.

 Personally I like graphs.   Everyday the TV news gives a number.  But they don't mention the day before.  And without that it's difficult to see the trend lines.
Anyone know where I could get historic (like last week) for Bay Area?  I suppose I could laboriously search for one day at a time...

The confirmed cases metric is really hamstrung by our inconsistent testing regimen.  I don't trust those numbers, and agree they're only useful for comparing rate of change against the deaths figures (which are more accurately recorded, even if post-mortem testing is also questionable).

The Financial Times here in London (I tend to cycle past their offices between my office and Borough Market to get lunch/coffee grounds) have finally opened up their data analysis page to the public without paywall:

They changed the dashed lines to no longer show the "33% increase in deaths per day" to marking out doubling times in days, which is a more useful set of landmarks.

The stars on those graphs also indicate when a nation called an official lockdown/quarantine order.  The UK, like NZ, announced a few days in advance: we don't have anything taking legal effect until Friday.
