Besides of FIRS3 Extreme economy, also FIRS1 is supported, for sake of compatibility with some old good scenarios.
Payment curve is change only if "flat payment curve" or/and "improved station ratings" options are selected AND appropriate economy (FIRS3 or FIRS1) are chosen.
I it up to you to have these economies really loaded, otherwise all will be messed up.
Decreased payment for passenger/mail works regardless of economy type.
Here is an example of payment curve with "flat payment curve", "improved station ratings" and "decreased passenger/mail payment to 2/5" options enabled:
Raw (primary) materials have low payment, but usually there is small delivery time and last visited station rating penalty.
Secondary resources have medium payment. Final products have high payment.
Recyclables payment is forced to be lower, because their production is overpowered.
Other payments modifiers are original ones modified by appropriate bonuses (more flat curve or improved rating).
