The above triggers may be better understood after reading California's county data monitoring documents (and particularly, Step 1: Active Data Monitoring) Some of the improvements in that document are better definitions of when data should be used, avoiding distortions caused/allowed by using recent but incomplete data.
Hopefully, this will avoid actions such as Orange County's (desperate?) calculation of % positive as 7.95%(where 8% would be too high) on page 5 of their variance attestation dated May 18, but using data for the week ending May 19, covering only 52% of the tests now showing for the week. Orange County does not post their % positive results that I have found. Calculating the ratio of newly diagnosed people divided by total tests (not individuals) gives them 4.5% for that week. OC's web site says: "Effective May 6, 2020, counts of Orange County COVID-19 tests performed replaced the count of people tested for COVID-19. This change more accurately reflects testing conducted by Public Health, clinical and commercial labs."
A calculation done this way is what is being alleged that Florida is doing with their public numbers.
Also, in San Diego County's data is a weekly graph of confirmed cases by 20-year age group. The changes in those numbers over time are interesting.
It does show an original (and long lasting) very small percentage of cases in 0-19, but that number has come up to be roughly 40% of the 40-59 age group (roughly equal population in both groups). The other 3 age groups (20-39, 40-59, 60+) are roughly in line with their population (using data before the incomplete period).
San Diego population age demographics:
0-19: 817.3K 25.21%
20-39: 1029.7K 31.76%
40-59: 832.6K 25.68%
60+: 562.9K 17.36%
