The Telegraph front page headline reads:
"Lockdown to continue until cases drop below 1,000 a day".
That's going to be a problem unless we more-or-less stop testing as SAGE say that false positives (for PCR) are between 0.8%-4% and Matt Hancock says 'about 1%'. So unless we do fewer than 25,000 (if rate is 4%) or than 125,000 (if the rate is 0.8%) tests per day, or whatever it needs to be in between, we are never going to find fewer than 1000 'cases' (ie positives) per day and therefore will have to remain in lockdown for ever. Even if no one is actually suffering from Covid at all.
