The most credible theory IMO is that it is not only probabilistic but also cumulative (in that you need to consume some number of virus particles to succumb to infection, and that number varies by person), but I don't know what period it clears/dissipates over. So it may be that 2 hours at 2.5m is as risky as 15 minutes at 2m on average, and that that 2 hours can be clocked up over the course of a day, but that's just an illustration.
There's so much about this we still don't know and it'd be great to say just be cautious but there's a point where that really hinders health in other ways, physical or mental. The riskiest thing I've done is probably either go for a blood test or shopped in a badly-managed supermarket. I could have avoided both but then I'd not know if my drugs were about to kill me and I'd have had a more limited diet and probably less money or had to travel and queue again elsewhere, none of which are good for me.
It's a big balancing act crossed with gambling. Good luck, everyone!
