I think it's better to ask this kind of questions here. I developed the civs, 1SDAN only merged them. So it is likely I know slightly better how the code works.
I used the same code that is used for the Tamils. That means that you it is gold_slider*trade_route_yield.
However, the value is stored as an integer. Taking your example, 30%*3 = 0.9. This is turned into an integer. IIRC, python rounds is down. So the value does probably not increase. Maybe the code should be rewritten so it is not lost.
