I think maybe some of the confusion lies in what this assessment tool means in terms of chance of "exposure". I think it is only predicting what the chances are in a group of a particular size whether or not at least a single person would test positive for covid? I don't think it takes into consideration any mitigation. So if I am in a group of 100 outside my "risk" is going to be quite a bit different in terms of getting covid from an infected person than if I was in a smaller inside space. Am I interpreting right?
