5 days? That's better than what the wife got (isolate for 2 days over a weekend too....).
The thing is, she's a dentist and walking back the dates was at work. OK so far, but her phone was on the reception desk (practice rules, plus her room being lead lined doesn't lend itself to good phone signal).
So if she got pinged... Why did none of the other staff she was working with get it as well? Not one of them...
Then there's the transmission controls in place being an order of magnitude better than most work environments (something about working with transmission sources, aerosol generation and generally staring people in the mouth for long periods of time) and have only tightened up since they were allowed to pickup the drill again.
Then there's the constant testing that she takes anyway ontop of being double jabbed (she managed it before my grandma did).
That evening we went to a local brewery for some food and a few beers. We both checked in, we both were there for the same period of time, so why haven't I been pinged?
The app has no sense of nuance or finesse. Even just letting you know where the contact took place would be an advantage (where you sat having a picnic in a breezy park with only one person nearby who tested positive or locked in an airless office with twenty someone others who came down with it? Who knows...)
