Can we discuss the BIG protocol? It might not be as strict as you think.

The Big Ten Conference will use data provided by each Chief Infection Officer (CInO) to make decisions about the continuation of practice and competition, as determined by **Test Positivity Rate** and Population Positivity Rate, **based on a seven-day rolling average**:Test positivity rate (number of positive tests divided by total number of tests administered):

Green 0-2%Orange 2-5%Red >5%

Bolding mine. So, if they include about 120 players per day, they would need 42 positive tests.

120 players * 7 days * 0.05= 42 positive tests

They aren’t testing positives every day. That would be a waste of tests. So assuming maybe 10 positive tests, they are still doing 110 player tests per day, most of which are presumably negative to drive the percentage of positive tests down.

110 * 7 days*0.05= 39 positive test

It would take a pretty significant outbreak to meet the BIG threshold.

​

Edit to clarify: I think the devil is in the verbiage. If it said Player positivity Rate or case positivity rate, this would be different. But it says TEST positivity rate. Positive tests, therefore, should not roll over. They should be counted as one test on one day, not 7 tests over the course of a week.
