I found out how the mod computes trading costs:

returns a value between 0.0 and 1.0

and  rounds the result to the closest integer. is an value which is added to the trading entry in the code.

this part sets the trade cost to 1, if it is < 0

So we can get:

minCost = baseCost * 0.75  (rounded to closest integer)

maxCost = baseCost * 1.25  (rounded to closest integer)
