Here’s what I don’t understand about those in the UK news articles arguing that people infected will be missed by the lateral flow tests. How long does current test result average? Wouldn’t catching more cases sooner, even if you miss some, decrease the infection rate overall drastically?

This seems like a no brained to test every day or every couple days at a price point this low. If you could do that for most of the population, then in 3-4 weeks you may be near zero on cases or at least drastically reduce the infection rate.
