Well, I should thank the two experts who knew so much that they didn't need to look at the chart. I'm sure your answers will help all the anxious people on this forum immensely.
And avonelle, I'm sure you don't drive to work every morning, right? Because, if I'm not mistaken, isn't there is a risk that you will die in a car accident?
If you are asking for opinions, here is mine: the chart doesn't mean squat to anyone who had a risk because a risk is a risk... no matter how small the risk, it is still a risk. You can be told that your exposure was about a 1 in 2,000 chance... but would you just accept that and be like "Ok, no way I got it- I'm good to go" and then never be tested? No, because as small as the risk is- it's still there. What if you happened to be that 1 in 2,000? Someone has to be the 1. Granted, it is always good news to hear something like you have a 1 in 5,000 chance rather than 1 in 10 chance... but a risk is a risk and I think quantifying risk levels into a chart is a waste of time and effort.
