Calculation of Wealth-Bonus - Need help please

[Pico2016]

Dear members,

i have problems in understanding some of my wealth-bonuses. Hopefully you can help me with this.

In my actual rome-game i get superb bonuses in agriculture and i simply dont get why.

I get +83% in my cities Neaples and Ariminum. I tried to understand this number but i only get it to +58% as you can see below:

+20% Agriculture trough faction (Junier),
+10% wealth from all sources (settlement II, Rome)
+10% agriculture (amphora kiln in Rome)
+3% agriculture trough research (overall)
+1% agriculture trough region
+5% agriculture trough season (summer)
+4% agriculture trough settlement (II) (olives)
+5% overall wealth trough patrouilling army

= +58%

But there is still 25% left which i can't explain.
I made screenshots for you, so you can follow my numbers. And hopefully the screens help to discover what i dont see actually
I mean, it wouldnt bother me if the difference would be some percent, but 25 is quite huge and i really want to understand this.

Also i'm not able to explain the industry-bonus of 41%, i just get 20% when i try to calculate.

The screens are german, so i hope you can understand.

Thanks for any(!) support.

Kind regards
Pico


P.S.
please excuse my basic english.

Noone truly understand how the game engine calculates the different bonuses and penalties.

There may be another source also, there are a lot of effect sources in vanilla and even more in DeI.

But, also, Flash is right Some effects are added, some are multiplied, some half work. Its...oddly coded in the game.
