Testing levels in several states have gone down during periods when their positivity rate is increasing. This is the opposite of what you would expect, which is that states ramp up testing as their positivity rate increases. In Delhi, for instance, between June 3 and June 11, the seven-day average of daily tests went down from 6,540 to 5,001 even as the positivity rate kept rising from 18.3% to 27.7%. Delhi incidentally now has the highest percentage of tests turning positive, over a quarter of them. There are no states with positivity rates in double digits barring Delhi and Maharashtra.
