With the numbers going the way they have been for the past month - a plateauing of sorts according to the government's dashboard - why all the rush?
And how is anyone without a supercomputer going to make sense of a rolling programme of 100m + tests per week if we all take part? Ah, we won't all take part though, and many tests will not be done correctly at home, that will make the results patchy, at best, and virtually irrelevant at worst.
I also note another three word something - Covid status certificates - instead of vaccine passports. That's sure to make us all sign up.
The seven day average for cases for the past five weeks are fairly flat at around 3500 p/d. Death on the other hand are averaging about 100 per day and falling. They, along with the ONS (10s of 1000s of random volunteers) results have worked good enough thus far, just keep on monitoring.
