Once again, I have no idea what you are going on about. Is the spread of Covid-19 described by an exponential growth function? Yes. Does my graph show that? Yes. Do my data points fit a theoretical curve determined mathematically? Yes.
Beyond that, there is no need or use for high level calculus. Calculus just does not describe biological processes until you get down to the atomic/molecular level. And even then, most of our calculations don’t rely on calculus.
The beauty of the built in Excel functions is that I don’t have to make macros to do exactly the same thing. Which I have done, back in the distant past before I really understood Excel.
I really have no idea what your profession is, but it is painfully clear that it has nothing to do with the life sciences.
You claim I should listen to experts in other fields? My experience is working in multidisciplinary teams with epidemiologists, statisticians, physicians, veterinarians, masters of public health, microbiologists, etc. etc. I highly value the input of other experts WHEN IT IS RELEVANT. You have yet to contribute anything relevant.
You didn’t and can’t respond to a single point I made about the math you are using. I acknowledge the value of data collecting. But if you think you can extrapolate from it, which was ALL I ever cautioned, your just being stubborn. Please go do whatever you want. Let us all know when you have predicted the future.
