city improvements

[omnibus]

Hello, I'm new in this forum and have a question that might have been discussed already:

How exactly multiplicative effect of city improvements works? If I have e.g. a mill, my production is 50% higher. If I add a factory, is the other 50% increase calculated from original amount (i.e. before mill) or from the actual amount (i.e. with the mill). The same for marketplace+bank etc. How does presence of merchants& workers affect that?

Thanks

the 50% increase is calculated from your base production.
for example, you have 10 guys working in the field, and they produce 100 production. A mill would increase that by 50, so after building a mill, you production would be 150. Building a factory will rasie it by 50, (100-base production * 50%) , so after building factory, you will have 200 production
