cargo,
I think your confusion concerning the lag is a result of you you trying to interpret a bunch of raw data without the requisite expertise.
You could just listen to the plain English explanations from numerous epidemiologist.
It’s like if you handed a print out of the the ATIS to passengers instead of just saying it’s going to be warm and sunny with light winds.
hey just my opinion. More power to ya
(insert 20 hyperlinks here of epidemiologists saying the lag is 4-6 weeks from rising cases to hospitalizations/deaths)
