I would love to agree with you but I take the exact opposite viewpoint. Unless there is a standardized process with a fully compliant population you will never produce actionable data. People going in randomly (without strict guidelines) generates too many assumptions which dummy down conclusions. Already the misinformation, the politicizing of the virus, and the lack of transparency from the institutions has developed this into a problem. Just look at the results we have so far...Testing does a ton to help governments, countries, cities, etc decide how to scale their efforts. Depending on the results, a city could be in the 'ok, we're alright but this might get bad so let's get going' or 'my goodness we've messed this up, we need to lock it all down ASAP.'
