Why have they chosen Liverpool not Manchester for the testing? I am sure the rewarding Liverpool v punishing Manchester factor was real. This is human nature and political reality after all.
But it also depends on what you want the testing to show.
If it is declining case numbers that you can argue how the new testing method has helped achieve then Liverpool is the obvious choice. Because as my nightly reports have shown the case numbers have literally plummeted over the past 2 - 3 weeks and yesterday were sub 200. Not 500 as they were just pre tier 3.
And, yes, like Manchester and other cities likely driven by student returns.
Manchester had a great day yesterday to its lowest numbers in over two weeks and GM might be on the cusp of doing the same as Merseyside but right now its more likely to not show a dramatic effect from this new strategy. Its a gamble of one clearly already doing it versus one that might.
The testing strategy is worth trying so I am not criticising the choice of location here but these decisions are not always just based on where a place should be because it has most need at that point in time. There are multiple factors at work.
Of course, the data could easily change things over the coming days before it happens. Almost certainly why the Salford testing plan was halted. When students returned there numbers skyrocketed. As they did in many university cities.
The university and schools returns - which had to happen for the sake of the next generation - clearly were the main reason why numbers climbed faster in some areas than government hoped. But that impact is now waning and we may be readjusting to a more normalised (and slower) Winter uptick.
It might even prove that waiting for this to play out before doing a new lockdown will (probably by fortune not design) bring numbers down faster than they might had students been driving a lot of cases at the same time.
