The official data is not showing a doubling at all. I'm not seeing an exponential curve - yet.
I am referring to US data, which is doubling every few days now. May change.
Your graphic is a very poor one to read. It does not show the x-y coordinates because of the black background. I am sure you could have found a better graphic and not waste our time.
The problem is that the official data is incomplete. There’s not enough testing going on for us to really know what’s happening.
Of course, the rational response to that is “let’s do more testing” which is one of the lines PDJT is pushing, but the media’s reaction “OMG we’re all dead!”
