It just goes to show that concentrating on how many "positives" tests are out there doesn't really get us much. What's important is the rate of hospitalization and the "death" rate. If those aren't really going up, who really cares how many positives there are? An example from South Dakota. A church camp out in the Black Hills had an "outbreak" of the virus. Slightly over a 100 of all the campers (a good number of adults, don't know the ratio of adults to kids) tested "positives". Zero have been hospitalized as far as I know-- my brother knows one [a medical professional] who got sick. The "case" counters would say a "disaster", about a 30% infection rate. The people who are actually concerned about how sick the positives really are, would say, "what's the big worry"...?
P.S. The medical professional that my bro knows that got sick, that person was started on a "'quine" cocktail (hydrochloroquine- azithromycin-zinc) and felt immensely better by the next day. The person was early in being sick-- a key point...
I agree to get the best idea of what is going on, you have to look at all three metrics. IMHO I would say the three are rolling: weekly average positive rate, weekly average hospitalizations for covid, weekly average death tally from covid.
The problem with daily numbers is they are not updated much on the weekends, so there are big drops on the weekend and big climbs on Monday and Tuesday.
