1 month ago The bw_graph_tools documentation mentions:
__supply_amount__ (float) – The amount of the activity (not reference product!) needed to supply the demand from the requesting supply chain edge.
In the case of the USEEIO table - what is the difference between reference product and supply amount?

For a final demand of 100$, are the values of upstream inputs not rather low?
