CV and mad panic behaviour

[LP]

Go from zero. Basic math as you love to say.

I suppose assuming the contact tracing was a constant it might have some relevance, otherwise you must make adjustments for how that has changed over time to get a viable relative measure. Remember the argy-bargy over which state was better, that exists because they are/were different.

Also to be pedantic how each jurisdiction define a positive might be an issue, also how each jurisdiction positives, I'm not sure if we have a Federal standard yet.

Of course the starting point is relative when you discuss percentages, going from 1 case to 2 is 100% increase. Just like the original wave, the worst figures come early on, the real trend is only resolved after a much longer period.
