This graph has been used to predict new cases would rise for London in November 2021 at a time when Scientists using complex modelling methods said they would "plummet" (https://news.sky.com/story/covid-19-cases-could-fall-significantly-in-november-even-without-plan-b-modelling-suggests-12444117). At the height of the Omicron scare in mid December 21 again the graph predicted cases would plummet in January/February "irrespective of any measures that where in place in London" that has since come to pass.
