That's not even the crux of the issue, so maybe we should get a little introspective about our own qualifications while we're at it. The problem is that negative tests are counted each time, while positives are per-person. So one nurse could account for 100 negative tests, so the presentation is misleading.

The point I was making is that whether this is a problem or not is not a resolved scientific issue, which presupposes the data and presentation.

Furthermore 'this' is a 2 fold issue: do you count negatives more than once; and, do you count positives more than once? These are 2 separate matters; however, I would say counting negatives more than once is the least controversial part.
