I agree Doodledog, although I don't actually think there's much of a rationale behind the easing of lockdown anyway, apart from scoring positivity points from those who were fed up with being cooped up. Where I live, in the East of England (but actually London commuter belt territory), the infection rate doesn't seem to have shifted much, which I find concerning. It means that as one person recovers, another one becomes ill, so R=1.
In Germany each small area is being monitored and treated accordingly. Unfortunately, local authorities in the UK have had that capacity stripped out through successive cuts. IMO the attempt to control this from the centre in a top down way is a huge mistake.
