The R0 in Victoria stopped decreasing; effective policing may be the answer

The R0 in Victoria stopped decreasing after the 25th July (in very light blue for the Australian R0). Action taken by the Victorian government ​to enforce policing of people in isolation will start the R0 deducing again.

The R0 had reduced to 1.1 (shown by the dark blue graph generated mathematically from values input into the blue box on the left), but did not reduce further. So near, but so far, from decreasing below 1.
