is there a Social Policy chart to show culture costs increase per acquisition?

I took a quick gander at the War Academy hoping for maybe a chart/spreadsheet that shows basic culture cost progressions even past completion of 5 trees. didnt see on in the stickies.

i dont need to know the numbers adjusted with things like wonders factored in or the liberty policy bonus (33% less increase for new cities) but i would like to see maybe a spreadsheet with the costs for each progression increase AND each city cost increase.

im having problems managing the amount of cities and their culture buildings and seeing if its worth another city or not.

is there something like that available somewhere?

(just lost a rage-quitting culture game with Siam and i just want to reassess my plan.)

the number crunching thread has the updated formula near the end of the thread.
all you really need to know is each city is +15% increase from base on standard or smaller sizes, or +10% with representation. having 4 cities increases costs to 1.45x of base, or 1.3x with representation. note that with 4 cities this makes representation slightly better than the piety finisher (1.3 / 1.45 = 0.897, slightly more than 10% decrease in costs)
3 or 4 controlled cities plus some puppets is a pretty optimal empire size for a culture game, mainly due to the ability to abuse legalism for 4 opera houses or museums.

thanks for the info. ive been doing culture with 6 cities and its taking me deep into the 1900s on standard. i might have to try with 4 (what i typically do in science vics) even though i hate giving up the land area.

puppet a neighbor, there are income benefits to that and no social policy cost increase.
