We really need to start teaching people how to do a non-linear regression. Why would you ever do a parametric fit on over 100 data points in a 1D input space?

I don't know why you're getting downvotes, maybe the statement is expressed a a bit too absolutely, but with large datasets and few dimensions there are almost no downsides to flexible regression approaches (LOESS, splines etc.) There is no reason to fit an exponential regression with this much data.
