Hi Paul, I haven't created any forecasts beyond 2020. But it's quite straitforward to do that in Jupyter notebook. You can call the predict function of the model and give future s2f values that are based on assumed flow and market cap. Or you do the match in a power law function with coef and intercept obtained from the model. It says a price will be exp(-1.385) * S2F ^ 3 in my understanding. Please note that data points used in this article might not so accurate because of public API and the calculation for flow and S2F ratio values. Thanks.
