In retrospect they should have required all teams to arrive within 1-2 days of each other, instead of spread out over a week or so as it actually happened. That way, all the initial arrival positive tests get announced at once, as do the ones from a few days later that may or may not have been caused by exposure in the bubble. This lets everyone make a clear, rational decision as to whether to go forward while knowing all the numbers at once. Instead, everyone is subjected to the drip, drip, drip of new results, many first publicized by an anonymous Twitter account, which seems regularly to be accurate, but the process hardly inspires confidence.
