Hate to be a buzz kill, but there isn& #39;t nearly enough data to draw conclusions about NYC. Here& #39;s a chart of Italy& #39;s new cases. There& #39;s a clear weekend effect, where new cases drop dramatically Fri-Monday, before normalizing midweek. I see no reason why that can& #39;t happen here...

... There was a clear mechanism causing that dynamic in Italy: fewer tests were both administered and completed over the weekends. No clue whether that mechanism is at work here, but you can& #39;t draw conclusions without considering that dynamic.
