Exponential growth - I think we are there.

The data at https://coronavirus.1point3acres.com/en is pretty stark.

We are at 2969 cases - an increase of 658 today alone.

On March 1, 91 cases, 20 new
March 5, 236/75
March 10, 1040/289
today March 14 2969/658

If we are on the pathway to the Italian experience with this - Italy has 350 cases per million people - probably due to totally inadequate or non existent testing, we are only at 8.5 cases per million people. The shit may be just beginning to hit the fan.

A bit more analysis - Italy went from 80 (Feb 22) to 250 (Feb 24) to 1000 (Feb 29) to 3000 (March 4) - 10000 (March 10) to 21000 (March 14) - to use numbers similar to ours so far.

2 days - 5 days - 4 days to go from 80 to 3000 - Italy

4 days - 5 days - 4 days to go from 90 to 3000 - US - eerily similar. This means we may be at 10,000 in 6 days (March 20), AND AT 20000 by March 24, if the same patterns hold.

Place bets on the day we hit 5 figures. And 6 figures. My guess is, frighteningly soon. bullwinkle428 Mar 2020 #5

Right now, if you plot the data out 40 more days, we're still on the flat part of the curve. About 15 more days and we're at a half a million - and then it starts racing up.

(That's on a polynomial that matches very closely. The closest purely exponentaial has us "flat" for about the same - but the uptick is much steeper at day 15 from now.

I just hope that we started strong measures soon enough.

Polynomial curve- we hit ~1 million in about April 18.
Purely exponential - we hit ~ 1 million April 7
