Re: Decentralised
"They are really good at it."
It depends what you mean by good.
The report on the Beeb web site says they've picked up 4,000 who then tested positive, about 25% of the known cases. But they sent out 79,000 alerts so that looks like 95% false positives. What would the hit rate have been if they'd sent out 79,000 alerts to random people?
